ROMControl: Allow Custom Icon Tinting Option (2/2)

PS3:  I'm a moron.  Working now.

For Your Consideration:
Zaph informed me that he believes colorizing icons slows the Rom down.
As y'all know; I upload commits because I find it entertaining to play
with the code a little bit (albeit very frustrating).  Often I don't intend
to even use the commits I upload.  That being said, I did see two individual
requests for this to return.  And a few "likes" on said requests.
You (the actual developers) will have to duke this out.

Zaph.  Chime in.  I don't mind you "-1ing" a commit on the grounds of
disagreeing with it.
