F-Curve Modifiers: Basic GUI for Generator Modifier working
* Currently, this only works for the 'Expanded polynomial' mode, but this will be expanded to include the other modes too. Now you can modify the values and interactively see the graph in the view change.
* Disabled the backdrops (modifier 'panels') temporarily, as ROUNDBOX UI elements currently swallow all events, which is not good.
Note: the code here still uses the old-style UI definition code since the new stuff is still under heavy construction.
