Better icon names/ easier icon themes (fdo#30425)

Hi, Michael, Stefan.

I'm ok with that. If we can count how many duplicate images (for UNO
commands) does exist, we could know it is pointless or not.

I suppose

Hm... I didn't mean to renaming UNO commands, I just said that how it
is implemented leads to some duplicates.

What about other icons, then? There's a lot of inconsistency and
"encripted" names... [1]

That's a way to go. Simple to implement and simple for an
artist/designer/"themer" to do it also.

Yes, that's it =)
But the concerns about name sizes pointed by Meeks ruin this
concept... Unless things like this [2] show duplicate images.
