Windows: Improve Freetype font database registry check for fonts

Some non-scalable fonts like "Courier" list some numbers after the font
name in Windows registry, e.g. "Courier 10,12,15". These are not part
of the font name and therefore confused the algorithm looking for font
files. Improved the algorithm to ignore this kind of number list.
Single numbers are still expected to be part of the font name.
