ANDROID: disable compression of zip-files in apk

Do not compress zip-files added to the apk archive. This is very slow on android 2.3 devices if the zip-file is big (e.g. modern.zip theme) and devices with android < 2.3 do not support assets with an uncompressed size greater than 1 MB at all.

As most zip-file entries (like themes) are just stored and not compressed, zip-file assets are recompressed before adding them to the apk to avoid wasting space.
ANDROID: increase required NDK and SDK version numbers

Android NDK 5 and SDK 7 (Android 2.1) are needed to provide full multitouch support. Otherwise MotionEvent.getPointerCount() and  MotionEvent.getX(int) are not available.

In addition GLES2 headers are only available in Android 2.1 and newer revisions.
