Updated Android build tools version, which bumped minimum deployment target to API 14

Also added native code to the Android gradle project, which allows using gradle or Android Studio to build the entire SDL application without a separate ndk-build step.

Why is API level 10 the minimum required?
Why is API level 14 the minimum required?
================================================================================
API level 10 is the minimum required level at runtime (that is, on the device)
because SDL requires some functionality for running not
available on older devices. Since the incorporation of joystick support into SDL,
the minimum SDK required to *build* SDL is version 16. Devices running API levels
10-11 are still supported, only with the joystick functionality disabled.
Support for native OpenGL ES and ES2 applications was introduced in the NDK for
API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
has since then been obsoleted, with the recommendation to developers to bump the
required API level to 10.
The latest NDK toolchain doesn't support targeting earlier than API level 14.
As of this writing, according to https://developer.android.com/about/dashboards/index.html
about 90% of the Android devices accessing Google Play support API level 10 or
higher (March 2013).
