Corrected BB costs for Glyphs

BB costs for glyphs are incorrect - the cost for a 10.0 talisman with a 10.0 glyph is 30BB, not 60 - the glyph requires a toolkit, but does not cost any BB to insert into the talisman. Reduced the cost of glyphs by 30BB to reflect the actual cost.

I can't get it to build on my machine, so I'm not sure if there are any tests that I should have changed.
