Include windows.h in a single point in the source, so we can be consistent about the definition of UNICODE and have core utility functions for Windows that all modules can share.

I think this also fixes the bug relating to non-latin characters in filenames, since UNICODE wasn't defined in SDL_rwops.c

rename : src/SDL_android.cpp => src/core/android/SDL_android.cpp
rename : src/SDL_android.h => src/core/android/SDL_android.h

Implemented SDL_SetWindowTitle(), which turned out to be fairly complex

* Formalized the interface with Java methods in SDL_android.h
* We don't need the feature system, at least right now
* Fixed waiting for the SDLMain thread

Build the SDL library as a shared object on Android, so it will work correctly with SDL_image and SDL_ttf.

FIXME: Still need to pass some arguments - can we get them from the Java class?

- Moved to 'project' instead of 'testproject'
- Removed extraneous .c files
- Removed the android_libs folder (that was against the NDK agreement anyway)

- Added 'feature' enable/disable so we're not running accel/sound/whatever in Java when we don't need to be
- More work on the sound system. But it still crashes pretty horribly, not sure why yet.

- Initial support for touch and key events
