[Bf-taskforce25] RNA Naming convention

[Campbell Barton]

Could identifier names starting with numbers be forbidden with RNA?,
this is messing up python which cant do
  bpy.curves['MyCurve'].3d = True

(using setattr works but is ugly syntax)

On this topic it would be good to decide on toggle prefix

curve.use3D
curve.enable3D
curve.do3D

This brings up another issue, some options are inverted (buttons where
TOGN is used)

The flipping of the flag could be done within RNA, otherwise we'll
need to have naming conventions that show this...

curve.useSpam -> curve.dontUseSpam
curve.enableSpam -> curve.disableSpam
curve.doSpam -> curve.noSpam

If RNA doesn't give some flipped bit functionality enable/disable seem
the best options to me.
