It seems that the Sunday hangover was as much thanks to a cold or flu as grog.

- I'll set glyph types on all glyph instances and just update them as necessary when the user makes corrections.
- Adding a few more element types to database. The range of types is getting a bit broad (such as 'tail5topGraceSlash' for the flag/tail of an upright acciaccatura).
- Need to add a button to confirm match but not update detection params in db. Done.
- Need to do something clever when user manually sets glyph type. Must highlight instance of glyph on score and on change, update db. Might need a checkbox to toggle db updating.
