Fixes

• Provide access to addLocationLabel and addLocationLabelDescriptor. These are already present in the FontTools DesignspaceLib.

• Add a method startLog to be called when we want to see the log after starting without debug.

• Fixes an issue with locationToDescriptiveString: check if the discrete location is None

• self.loadFonts() added to generateUFOs(), makeInstance, makeOneInstance, makeFontProportions, makeOneGlyph, makeOneInfo, makeOneKerning. Because it is not always clear whether the fonts were indeed loaded. I acknowledge this is a small overhead, but it seems justified by the time spent in confusion if it is not called.

• Round the instance kerning data when asked.

• Respect the glyphnames listed in font.lib public.skipExportGlyphs when making UFO. This creates a mechanism to remove specific glyphs from output, to allow test fonts to be made from designspaces that contain incomplete, unfinished glyphs.

• Version upped to 1.13.2.
