I'm sure its pretty self-explanatory but I'll do it anyways

I was thinking that toribash should have an option to have an avatar preview much like how we can preview our posts.

The reason for this is that it really is cumbersome to pick an avatar and go through trial and error to see if it was formatted correctly (right size and shape), and constantly coming back.

might just be me being lazy, but since we have a "preview post" we should have a preview avatar imo.
