-----------
NLA SoC: Separating F-Modifier UI drawing into its own file
* F-Modifier UI drawing/handling is now defined in a separate file so that it will be more suitable for inclusion into the NLA Editor's buttons.
* Started removing F-Curve dependence from the modifier drawing code, which wasn't strictly necessary
* Fixed F-Curve RNA wrapping to correctly use FPoints instead of the bulkier BPoints. Although nobody was likely to have encountered bugs here yet, this would almost certainly have contributed to some segfaults/data corruption along the track.
