Prepare dependency macros for Android. Move curl_configure to HttpPlugin as its only needed for it.
Android cmake: Cleanup file and update to new style of passing dep locations to cmake instead of env variable. Added to-be-committed curl and zziplib.
CMake fixed for rel/debug libs. I always assumed that the optimized applies to all the items before debug is passed. Apparently this is false and needs to be defined for each :)
Android: Make tools/Windows/BuildDeps.cmd handle both VS and Android NDK cross compilation in a single file. The main differences are very small and can be parametrized, no sense in keeping 2x files manually in sync. Implements building all dependencies (except zlib as always shipped with Android OS). I will refactor the android stuff later to tools/Windows/Android, right now I cant look at this anymore as have been cruching it to get building 9h straight. NOTE/TODO: The resulting Turho build has not been tested on actual device yet.
