Tamito Kajiyama b408d8af31 Freestyle Python API: Updates and speedups for the parameter editor
In addition to D319, this patch updates the parameter editor, the UI of Freestyle.

Using new API functionality and experience gained in making D319, this patch
provides a quite noticable speedup for commonly-used Freestyle linestyle modifiers.

As this patch touches a lot of code (and mainly the foundations) it is likely that
mistakes are made.  The patch has been tested with a regression suite for Freestyle
(https://github.com/folkertdev/freestyle-regression-tests/tree/master), but testing
with scenes used in production is very much appreciated.
