Shorter Option for Find/Replace Panel

From issue #22

I've added the option `findreplace_small` to make the panel a little smaller so it doesn't overlap with the status messages. I think the option name could be improved but I can't think of any other name.

I'm really no expert so I might be doing something wrong.

Let me know if I can help in any way.
