Bump version to 0.11.3 and update toxcore version in static build script

File transfers initiated for offline friends are now
added to a queue and initiated all at once when the friend
appears online.

+
+#### OS X Notes
+Using [Homebrew](http://brew.sh):
+```
+brew install curl qrencode openal-soft freealut libconfig libpng
+brew install --HEAD https://raw.githubusercontent.com/Tox/homebrew-tox/master/Formula/libtoxcore.rb
+brew install libnotify
+export PKG_CONFIG_PATH=/usr/local/opt/openal-soft/lib/pkgconfig
+make
+```
+
+You can omit `libnotify` if you intend to build without desktop notifications enabled.
+
+## Compiling
+```
+make
+sudo make install
+```
+
+#### Documentation
+Run `make doc` in the build directory after editing the asciidoc files to regenerate the manpages.<br />
+**Note for developers**: asciidoc files and generated manpages will need to be committed together.<br />
+**Note for everyone**: [asciidoc](http://asciidoc.org/index.html) (and this step) is only required for regenerating manpages when you modify them.
+
+## Notes
+
+#### Compilation variables
+* You can add specific flags to the Makefile with `USER_CFLAGS=""` and `USER_LDFLAGS=""` passed as arguments to make, or as environment variables
+* Default compile options can be overridden by using special variables:
+  * `DISABLE_X11=1` → Disable X11 support (needed for focus tracking)
+  * `DISABLE_AV=1` → Disable audio call support
+  * `DISABLE_SOUND_NOTIFY=1` → Disable sound notifications support
+  * `DISABLE_QRCODE=1` → Disable QR exporting support
+  * `DISABLE_QRPNG=1` → Disable support for exporting QR as PNG
+  * `DISABLE_DESKTOP_NOTIFY=1` → Disable desktop notifications support
+  * `DISABLE_GAMES=1` → Disable support for games
+  * `ENABLE_PYTHON=1` → Build toxic with Python scripting support
+  * `ENABLE_RELEASE=1` → Build toxic without debug symbols and with full compiler optimizations
+  * `ENABLE_ASAN=1` → Build toxic with LLVM Address Sanitizer enabled
+
+* `DESTDIR=""` Specifies the base install directory for binaries and data files (e.g.: DESTDIR="/tmp/build/pkg")
+
+#### Environment variables
+* You can use the `CFLAGS` and `LDFLAGS` environment variables to add specific flags to the Makefile
+* The `PREFIX` environment variable specifies a base install directory for binaries and data files. This is interchangeable with the `DESTDIR` variable, and is generally used by systems that have the `PREFIX` environment variable set by default.<br />
+**Note**: `sudo` does not preserve user environment variables by default on some systems. See the `sudoers` manual for more information.

-Toxic is a [Tox](https://tox.im)-based instant messenging client which formerly resided in the [Tox core repository](https://github.com/irungentoo/toxcore), and is now available as a standalone application.

+
+[![Toxic Screenshot](https://i.imgur.com/TwYA8L0.png "Toxic Home Screen")](https://i.imgur.com/TwYA8L0.png)
 
 ## Installation
+[See the install instructions](/INSTALL.md)
 
-### Dependencies
-##### Base
-* [libtoxcore](https://github.com/irungentoo/toxcore)
-* [ncurses](https://www.gnu.org/software/ncurses) (for Debian based systems, 'libncursesw5-dev')
-* [libconfig](http://www.hyperrealm.com/libconfig) (for Debian based systems, 'libconfig-dev')
+## Settings
+Running Toxic for the first time creates an empty file called toxic.conf in your home configuration directory ("~/.config/tox" for Linux users). Adding options to this file allows you to enable auto-logging, change the time format (12/24 hour), and much more.
+You can view our example config file [here](misc/toxic.conf.example).
 
-##### Audio
-* libtoxav ([libtoxcore](https://github.com/irungentoo/toxcore) compiled with audio support)
-* [openal](http://openal.org) (for Debian based systems, 'libopenal-dev')
-
-##### Sound notifications
-* [openal](http://openal.org) (for Debian based systems, 'libopenal-dev')
-* [openalut](http://openal.org) (for Debian based systems, 'libalut-dev')
-
-##### Desktop notifications
-* [libnotify](https://developer.gnome.org/libnotify) (for Debian based systems, 'libnotify-dev')
-
-##### Documentation
-* [Asciidoc](http://asciidoc.org/index.html) (only required for regenerating manpages)
-  * Run `make doc` after editing the asciidoc files to regenerate the manpages.
-  * **NOTE FOR DEVELOPERS**: asciidoc files and generated manpages will need to be commited together.
-
-### Compiling
-1. `cd build/`
-2. `make PREFIX="/where/to/install"`
-3. `sudo make install PREFIX="/where/to/install"`
-
-### Compilation Notes
-* You can add specific flags to the Makefile with `USER_CFLAGS=""` and/or `USER_LDFLAGS=""`
-* You can pass your own flags to the Makefile with `CFLAGS=""` and/or `LDFLAGS=""` (this will supersede the default ones)
-* Additional features are automatically enabled if all dependencies are found, but you can disable them by using special variables:
-  * `DISABLE_AV=1` → build toxic without audio call support
-  * `DISABLE_SOUND_NOTIFY=1` → build toxic without sound notifications support
-  * `DISABLE_DESKTOP_NOTIFY=1` → build toxic without desktop notifications support
-
-### Packaging
-* For packaging purpose, you can use `DESTDIR=""` to specify a directory where to store installed files
-* `DESTDIR=""` can be used in addition to `PREFIX=""`:
-  * `DESTDIR=""` is meant to specify a directory where to store installed files (ex: "/tmp/build/pkg")
-  * `PREFIX=""` is meant to specify a prefix directory for binaries and data files (ex: "/usr/local")
-
-### Troubleshooting
+## Troubleshooting
 If your default prefix is "/usr/local" and you receive the following:
 ```

+Toxic Scripting Interface
+=========================
+
+A Python scripting interface to `Toxic <https://github.com/JFreegman/toxic>`_.
+
+
+Getting Started
+===============
+Toxic is compiled with Python support by default. To access the scripting interface, simply import "toxic_api" in your script.
+
+Scripts can be run by issuing "/run <path>" from toxic, or placing them in the "autorun_path" from your toxic configuration file.
