[ubuntu-art] [Breathe] Wiki cleanup.

[Cory K.]

I removed/commented out some things to reflect the current front-runners
on the Submissions page.

I'm sure none of are sure about optical or dictionary but I think the
stuff below is a bit more solid.

I can't make up my mind on *-development. :)

And just a reminder, there's no shame in grabbing something from the
Oxygen set and modifying that. :)
