Added translations, used JNIEXPORT JNICALL
While not strictly required (many NDK examples do not use them), it is technically correct to use JNIEXPORT JNICALL for the JNI calls.  Also, I noticed that changing the language on my phone to one of the added languages doesn't actually do anything (it always just stays in English).
front: Update version in manifest
... and that APP_OPTIM slipped through again.
Merge branch 'master' into experimental_cheatsMenu
front: Fix game activity close on launch
Without the thread join, if you press an option to start the game before the cheats options are finished being populated the game activity will close and drop the user back to the play menu.  I still don't particularly like the UI thread being blocked here, so I will probably try and pass things to TaskHandler.  This will require handling the case where an impatient user precess Resume or Restart more than once (i.e. don't start a second task to launch the game if one has already been launched).
