NLA SoC: F-Modifiers working on NLA Strips

* Using the Ctrl-Shift-M hotkey, F-Modifiers can be added to all the selected strips.

* F-Modifiers can also be added/tweaked from the NLA N-Key properties. The UI now uses the same code as for the graph editor ones.

The UI drawing here is currently messed up from the NLA side, since it seems combining normal layout stuff and old-style uiBlocks doesn't seem to work too well (BUT! the buttons are at least functional).
Next up, I'll need to recode the buttons panel for the Graph Editor so that all of the drawing can be migrated over to use the new layout engine.
