BGE Py API

* Removed modules Expression and CValue, neither were ever available.
* Added GameLogic.EvalExpression(exp) from the Expression module, evaluates an expression like the expression controller (not sure if this is really that useful since python is far more advanced).
* resetting the original blend file path didint work (own fault == -> =)
* Py3.x PyModule_Create didnt allow importing since it didn't add to sys.modules,
  Looks like they want us to use init-tab array, but this doesn't suit us since
  it needs to be setup before python is initialized.
* Documented GameLogic.globalDict
