This is my second approach on adding kerning support for the 3DText objects.
For a reference here is my first approach: https://developer.blender.org/T47725
Kerning is added by, keeping the Freetype2 Lib loaded and the data for the font face within the vFontData object.
So FT_Get_Kerning can be accessed while the vFontData exists.
I hope the code fits to all the standards!
Any kind of feedback is appreciated,
