some more cleanup:
- made structure in source/gameengine/PyDoc/bge.events.rst to be able to crosslink properly
- cleaned notes and warnings syntax, and also now they are always the last elements after all the other tags
- substituted some lists of possible values of a parameter with links to lists of values (not finished)
like in bge.types.html#bge.types.SCA_PythonKeyboard
- uncertain about some values, like in http://www.blender.org/documentation/250PythonDoc/bge.types.html#bge.types.SCA_ISensor.status
(list of KX_SENSOR_INACTIVE,... etc aren't documented or non-existant, will investigate)
