[Bf-python] Attribute casing

[Yehoshua Sapir]

How should attributes be cased?

For my MTex patch 
(https://projects.blender.org/tracker/index.php?func=detail&aid=2869&group_id=9&atid=127) 
I have for example the following:

mtex.colfac (factor for color mixing)
mtex.correctNor (the "correct nor" button)
mtex.mtCol (mapto "Col" button)

Some thoughts:

- I remember reading somewhere on the wiki that to conform to Python, 
everything should be cased like "correctNor".

- colFac looks odd and is slightly harder to type than colfac. Perhaps 
it should be named "colFactor" or something like that anyway?
