Feature Request: implement gameplay improvements from Funsize

[yukichigai]

Funsize, aka the Android and iOS release of the game, included some gameplay improvements that may be desirable as optional features for dethrace. Specifically, I am thinking of:

• Opponents/Cops who are pushed off the map automatically recover themselves instead of being wasted.
• Power ups which are hit by Opponents/Cops are applied to the car that ran into them, or globally for effects like Pinball Mode, etc.

These would be optional enhancements not enabled by default, but available for those who want them.

In addition to that, the "medals" from the mobile versions could be implemented, that show in which way the level was completed. Also, an option to import better textures from that release would be nice.
