Find next when pressing enter with find dialog open

[jrowny]

When the find dialog is open, pressing enter should continue to find the next elements like F3.

Currently, if you press F3 with the find dialog open, it removes the text instead of finding. NJ says this works on MAC, so maybe a windows only issue.

seems if I manually type something in find, then press F3 it works, but not Enter, it just closes. I think this only happens if you have pressed ctrl-F with some text highlighted but it needs some testing.

Reviewed. Move to backlog as part of our official find UI story.

I've added this to the main user story for polishing up the Find UI: story 260.

@jrowny: the bug where even an explicit Find Next (F3/Cmd+G) doesn't always work is #2104, which was fixed in a recent pull request. If you grab the latest from Git, explicit Find Next should work now.
