GSFontMaster.name is not the same as in Glyphsapp

Some fonts will have different GSFontMaster.name with glyphsLib than with Glyphsapp.

This is because GSFontMaster._joinName() uses the width, weight, customName order but Glyphsapp apparently uses the weight, width, customName order instead.

Start in Lib/glyphsLib/classes.py at GSFontMaster._joinName(), linked in the issue. Compare its width, weight, customName ordering with Glyphsapp’s weight, width, customName ordering, then verify that affected GSFontMaster.name values match Glyphsapp.
