Make the Android UI more like the desktop UI

I didn't like how the Android UI was nothing like the desktop UI. I made a few changes so it somewhat resembles the desktop UI. I switched to the light holo theme, (not supported in Gingerbread, but since Dolphin doesn't support Gingerbread it doesn't matter) made the game list rows alternate between white and grey, and darkened the file browser icons because they were hard to see with the holo light background.

I made a comparison video https://www.youtube.com/watch?v=c3h6rM2MYxo if you want to see what it looks like compared to the current theme.
