F-Curve Modifiers - Generator: Finishing off most of UI

Browse Source 
* Finished code for Expanded Polynomial and Factorised Polynomial UI's.
* Started UI code for 'Builtin Function' mode. There are still 4 controls to add there to use something other than simple mapping
* Finished/fixed up verification code for these so that values get initialised ok.
