A step toward a new user-friendly GUI for manipulating line style parameters.

This commit is just meant to give the new GUI framework a concrete shape.
There is no usefulness in newly introduced elements at the moment.

Freestyle options in render layers now include a pull-down menu named Control
Mode that allows you to choose either the Python Scripting or Parameter Editor
mode.  The Python Scripting mode is the conventional way of controlling
Freestyle by directly using style modules written in Python.  The Parameter
Editor is a new control mode that is intended to be used by everyone without
relying on Python programming.

In the Parameter Editor mode, you can specify multiple line sets for each
render layer.  A line set defines feature edge selection criteria, as
well as a line style for drawing the selected feature edges using specific
line stylization parameters.  Line style is a new datablock type, meaning
that a line style can be shared by multiple line sets (possibly those in
different render layers in different scenes).

Much more additions are anticipated in subsequent commits to implement UI
controls for specifying feature edge selection criteria and line stylization
parameters.
