Add support for Android 2.3+
There have been plenty of ppl involved in creating this version. I don't wanna mention names as I'm sure I'd forget someone so I just tell where help has been done: - The partial android versions done by various ppl - Testing on different android devices - reviewing code (especially the in core changes) - testing controls - reviewing texts A big thank you to everyone helping this to be completed!
