[Open Assets] Better CTF Graphics Mod

After seeing the CTF HUD not getting any changes, I whipped up some upgraded sprites to have them fit in with 2.2's sprites.

These changes include:

- New flag sprites
- Updated indicators when the player has the flag
- New CTF HUD

While this mod is mostly a graphics update for CTF, I also tweaked the following:

- New IT indicator and icon in rankings for Tag and Hide and Seek
- Fixed GO! and Results text inconsistency for Race, Competition, Match, Tag, Hide and Seek, and CTF
