Before I post this to the Google Play store, I wanted to let you guys test it first. There are only 2 minor changes.
1. Properly sleeps in the background when an emulator is launched (this should help battery and potential lag)
2. Changed default path for retroarch.cfg to /storage/emulated/0/Android/data/com.retroarch/files/retroarch.cfg (was previously /data/data/com.retroarch/retroarch.cfg). This should unify the config files (when retroarch launched standalone) and make it R/W. Pointing to /data/data was a hspin app bug. SORRY!
