UFO:Alien Invasion Code

* base/pics png crush.

* Android: huge GUI revamp in base management dialogs.

* Replaced most of tiny spinners with big thumb-friendly horizontal spinners.
* Modified dialogs: Research, Production, Market, Transfer, soldiers/pilots list in aircraft management.
* I would like to put Android/PC differences into some kind of config, like minimal list item height,
* however it depends on some hoardcoded values in C code, so feel free to revert my commit if you don't like it.
