Merge remote-tracking branch 'origin/greasepencil-object' into soc-2019-npr

GPencil: Change default value in python API

The gpencil_lines must be set to False by default.

GPencil: Set gpencil_lines parameter to False by default

GPencil: Fix problem when color is nofill in SVG

If the color in the SVG converted was nofill, the stroke had fill color in grease pencil and this creates glitches because the shape was not defined to be filled.

Now, the name of the color is checked to verify if the material is for stroke, and if only there is one material with this name, the fill is disabled.

GPencil: Fix error generating strokes with curves with 2 points only

The number of segments must be 1 if the number of control points is 2. The problem was with the closed curves.

Also added tag of the databalock.

GPencil: Apply curve radius as pressure for stroke point

When convert the curve, the beziert point radius is used to generate the pressure of the grease pencil stroke point and this allows to generate different thickness.

GPencil: Rename python API function from convert_to_gpencil to generate_gpencil_strokes

The problem with old name was that it implied that original object was removed, but the function only creates the strokes, so the new name is better.
