[android] Added build/debug configurations support. To use it:

- Go to project properties/C++ build
- Set additional parameter for ndk-build: NDK_DEBUG=1
- Go to "manage configurations" at the top left and rename active Default configuration to Debug
- Copy Debug configuration and rename it to Release
- Change ndk-build's parameter NDK_DEBUG=1 to NDK_DEBUG=0 in Release

Active configuration can be changed in the project's context menu
