Improved cmake build script for Android: - Error out when Ant or android can't be found - Attempt to find the NDK toolchain binaries on Windows and Linux instead of assuming Linux - Use find_program instead of find_path to find some binaries - ANDROID_SDK now refers to the Android SDK base directory - Fixed detection of android.bat on Windows - Output of the android tool is now shown so that success/failure is visible
