"Dynamic Sketch" patch, which adds timing data to GP strokes, by storing an inittime in each stroke (value returned by PIL_check_seconds_timer() func), and then a delta time for each of its points, relative to that inittime.

These timing data can then be used during conversion to Curve objects, to create a path animation (i.e. an Evaluation Time F-Curve) exactly reproducing the drawing movements.

Aside from this "main feature", the patch brings several fixes/enhancements:
* Stroke smoothing/simplifying will no more move the start/end points of a stroke (this was rather annoying sometimes!).
* Also optimized smoothing code (even though not really noticeable on a modern computer, it now uses less memory and runs faster).
* When converting to curve, you now have the following new possibilities:
** Normalize the weight values (currently, they will get "stroke width * 0.1", i.e. would range by default from 0.0 to 0.3...).
** Scale the radius values to your liking (again, currently they are set from stroke width times 0.1)!
** Link all strokes into a single curve, using zero-radius sections (this is mandatory to use the dynamic feature!).

Here is a small demo video: http://youtu.be/VwWEXrnQAFI

Will update user manual later today.
