Shefki:
	- Stash the DEFAULT_FONT and DEFAULT_FONT_SIZE so I can get people having the font problem to show me what's being stored.
	- Wrap the SetFont and SetAlpha calls in pcalls() which should prevent errors with them from breaking frames entirely.
	- Make the Vengeance fix backwards compatible.
Benjamin Staneck:
	- use a different ID for vengeance that works in 5.4
Shefki:
	- Remove unnecessary constants that I added on accident.
	- Hopefully stop some rare errors in LuaTexts about SetFont.
