Proposition: Change record function names to dataStructure_member

[jchnkl]

I'd like to propose to rename the record functions with the data structure name first.
E.g.: root_x_MotionNotifyEvent to motionNotifyEvent_root_x.
This has two advantages:
First, it reflects the namespace -> member mapping better.
Second, if you use a code completion engine, starting to type motionNo.. will automatically show you a list of all members of the data structure.

Since XHB is still in an early stage, I think it would not be to worse to change the API.
