Android: Added basic drop file support (thanks, "noxalus"!).

This lets SDL-based apps respond to "Open With" commands properly, as they can now obtain the requested path via a standard SDL dropfile event. This is only checked on startup, so apps don't get drop events at any other time, even if Android supports that, but this is still a definite improvement. Fixes Bugzilla #2762.
