Additional glyphs
Adding appendGlyphs function to FlxBitmapFont.
See https://github.com/AxolStudio/HFAdditionalGlyphsDemo for an example and details.
truthfully, while I want this feature of adding glyphs to bitmap text, I don't know if I want this specific glyph parsing method to be the defacto way of using it. I can't explore right now, but I suspect there are more generic ways to implement this, I'm afraid that adding {foo} parsing may mess or conflict with other text parsing systems, I also think there might be more generic ways to add glyph frames to existing fonts, and in general I want to add ways to split up fonts into multiple atlases for various reasons. once that is done, I think an adhoc system like this will be easy to implement, and will make a good external tool
