        Options/Units.lua
    - Make a variable name be less ambigious.
    - Convert a line into an if/else block since it feels a little long.

Kyle Buller:
    - remove the ArenaSpecIcon module for now
    - CastBar: force an info refresh on IEEU
    - go back to using unit events and register UNIT_PET for arenapet
    - whitespace
Shefki:
    - This commit should fully fix the problems people have been having with SetFont() errors.  If the font returned from GetFont is nil then use our cached font and size.  Size whenever font is nil will be an uninitialized value and so the existing fix would still throw errors when the size ended up being less than or equal to 0.
    - It doesn't make sense to call GetFont on a new FontString.  The flags should not be preserved, so just set the font and size and leave the flags as "".  The AddFontString call later will set the flags properly. If the font string already exists then you want to preserve the flags.
    - Remove some values I set to help debugging ticket #1050.
    - Remove the spell icon feature from weapon enchants.  This causes problems when the spell icon isn't cached before entering combat and isn't very useful since almost all temporary weapon enchants have been removed from the game.
