* Replaced the toolchain file with a new version based on [zuhowei's fork](https://github.com/zhuowei/android-cmake), which enables x64 builds as well as support for the latest NDK. This breaks compatibility with old build directories.
* Removed the STL dependency from **sfml-activity** rather than relying on *some* implementation implicitly linked by default.
* Deleted *project.properties*, which wasn't supposed to be part of the repository code. You have to use the Android SDK to recreate it (`android update project --path to/your/example --target 1 --name SFML-Example`).
* Made it possible to select a STL implementation to be used (default: `c++_shared`). Keep in mind that not all available configurations are necessarily compatible with SFML.
* Fixed linker flags to be compatible with Nvidia's Nsight Tegra for Visual Studio.
* It is now possible to compile the Android version using Nvidia's Nsight Tegra for Visual Studio (requires up-to-date CMake and `CMAKE_SFML_SYSTEM` to be set to `Android`; keep in mind that this is still experimental and requires further CMake updates).
* Updated and renamed some Android specific CMake variables.
* Made `armeabi-v7a` the default ABI for Android builds.
- Replaced @executable_path by @rpath for more flexibility
- Updated freetype and sndfile libs as follow:
install_name_tool -id "@rpath/../Frameworks/freetype.framework/Versions/A/freetype" freetype
install_name_tool -id "@rpath/../Frameworks/sndfile.framework/Versions/A/sndfile" sndfile
* Apparently, there were some leaks not reported as such
* Support for 32 bits computer is restored
* Fix memory leak in sfStringToNSString (related to #484)
* Unapply context when closing the window, freeing memory

Commit ac28902b57094518e40b138b691b91f0f8004604 is the last one before the introduction of ARC.
A current limitation prevents one library from depending on shared libraries.
As we have legal issues here (LGPL wants us to use shared libs of OpenAL-Soft and libsndfile), we're forced to use this homemade native activity which will manually load our shared libraries.
