Splitscreen Mod 0.3.2

While there have been lots of technical changes under the hood, there are only few changes that are really noticeable for the end-user right now. Anyway, they are important enough to make a new release. Although the mod is still an alpha version, for its limited and unfinished feature set, it works pretty stable now. Here's the included change log:

• Mod doesn't need to be started multiple times, before it
  works (fixes #3)
• Rumble signal when the controller code is ready
• sdl_controller_code shuts down properly
• detect when player is in a car (could be used for new
  controller mappings!) and lots of other technical
  improvements that future versions will make use of
  (new injected API network protocol etc.)
