BGE alternative run mode for python controllers.

Browse Source 
Option to run a function in a module rather then a script from a python controller, this has a number of advantages.

- No allocating and freeing the namespace dictionary for every time its triggered
  (hard to measure the overhead here, but in a test with calling 42240 scripts a second each defining 200 vars, using modules was ~25% faster)

- Ability to use external python scripts for game logic.

- Convenient debug option that lets you edit scripts while the game engine runs.
