Follow Path Constraint - "Animate Path" Operator

Added a convenience operator to the Follow Path constraint which adds a F-Curve
for the path (or the operator's "fixed position" value if no path is assigned),
with options for setting the start frame and length of motion. This makes it
easier for common users to just set up a quick follow-path animation where the
camera (e.g. flying around a set over certain number of frames).

A key advantage of this is that it takes care of the underlying math required
for setting up the generator curve accordingly (I've got some plans for making
this a bit friendlier to use later). Now, animating the paths is a one-click
operation, with the start and length properties able to be controlled using the
operator properties.
