GPencil: Allow import several SVG at time

For SVG is very convenient to be able to import several SVG in one operation. Each SVG is imported as a new Grease Pencil object.

Also, now the SVG file name is used as Object name.

Important: As all SVG imported are converted to Grease Pencil object in the same location of the 3D cursor, the SVG imported are not moved and the result may require a manual fix of location. The same is applied for depth order, the files are imported in alphabetic order according to the File list.
