Improve android tools warnings

* Fix incorrect message for  selected target SDK (Bulgarian symbols were used)
* Improve message for build tools when the prefix and suffix have the same version (>=22 <=22) - #900
* Rename supportLibraryVersion to supportRepositoryVersion and improve messaging as Gradle does not work with Android Support Library - instead it works with Android Support Repository.
