- Fix Android compilation issues

- Added a "cachesize" option (not available from the menu, but can be manually edited in players/options.txt, for example cachesize=200 means 200MB of cache). The hardcoded cache on windows/linux is 20MB, which is not enough for Hi Res cards (60 is better, 200 is great)
