Merge branch 'everyone-gets-a-hud' into 'master'

Whitelist HUD graphic changes from isgamemodified

Some people like the italics, some don't, some are crazy and want to do their own thing. In any case changing HUD graphics doesn't do any harm to anyone.

This allows changing the following replacements to work without tripping isgamemodified:

* The Score/Time/Rings text and numbers, colon, period, and minus sign
* The console font
* The "tiny" console font used in a couple places
* The level title font

I also removed some stupid redundant code related to the above in the process, and renamed some of the patches related to score/time/rings because they had inconsistent prefixes.
