v4.9a Release

Announcing the latest game-mode: Bot Royale.

For the casual gamer, play up to 12 players against each other in either team mode or last-robot-standing. Games are fast and addictive, and a nice distraction for the long summer months.

Some more bug fixes and tweaks especially under-the-hood. Unfortunately expect some more bugs due to those necessary changes: please report them in the forums.
