Hedgeroid: Fixed map preview again (might be a JNA bug)

also needs exclusion here

Hedgeroid improvements: - Moved frontlib initialization to a slightly better place - Added new JNA type ByteArrayPtr to move more JNA code into the frontlib package and to improve pointer type safety

Don't leave frontend in engine waiting state when there's error occured on attempt to start engine

Hedgeroid: Some code cleanup, adding a forgotten file

Slightly faster and slightly better templates #41 and #43

License change: With the agreement of Xeli, I changed the Hedgeroid license to GPLv2+ (from GPLv2).

drawn maps have a fixed 4096x2048 area right now

Hedgeroid: Final sprint to the deadline - Changed local game setup to use the new fragments from the netroom - Pulled team editing into the main activity menu / action bar - Cleanups, renames, anything to make the code look better ;)

move this section back to the connection code, and add an exclusion for air attack. probably should play a few portal games just in case

frontlib: Improved documentation of netconn, unified naming of a callback

*sigh*

engine: Don't overwrite isTerminated if it's already true

initModule really not needed for uRandom

Fix engine crashes on game end - frontlib now waits until the engine actually disconnects - engine does not write round-end stats to stdout anymore on mobile (caused crash) - Removed HWTerminate function binding for android (not threadsafe, better send "eforcequit" over IPC for the same effect)
