Technical: Restore version debug glyph in PUA

The test glyphs were a temporary measure, all the details required for displaying font weight and version are in the font name table. There are disadvantages of leaving the beta test/debug glyphs in the fonts. Unnecessary overhead, they need to be manually updated for each release.

We are going to be in perpetual beta, which means there will be at least
two versions in wide circulation: the "x.0" major public release, and
the "current beta". I'd suggest it's worth keeping the ability to
differentiate every release form every other, even as we go into a
public beta and release mode.

Keeping these in sync is going to be a time-consuming operation if done by manually, so I can quite understand the reluctance. I think the simplest solution might be to re-inject the desired glyphs on our side in a more pragmatic manner. The attached python script re-injects the nameID=5 version number into the 'uniEFFD' glyph slot; the same can be done for populating the font/weight. The grayscale grid has not been useful at all, so that should be dropped and hopefully replaced by a pixels-per-em readout similar to Deja Vu.

It's a proof-of-concept so It'll needs more work to cope with full-injection into a font that doesn't have the glyph slot already setup; the glyph and its name to be created, populated, given dimensions, and added coherently to the various other tables.

This is probably the simplest way to patch in any license changes as well; and have it as part of the .orig.tar.gz "upstream/package" build process.

Didn't have sufficient time to patch these back in, but can hopefully be done at a later stage.
