[Android] Ability to delete ROMs

[Mike]

The suggestion is to have an option to delete games inside Launchbox for Android.

People normally install hundreds or thousands of ROMs in Launchbox. It would be very useful if you could delete non-interesting games to prune down the total list of games. In the end you would only have the interesting games.

Added title to reflect this is an Android request since PC already has this feature.
