Add a preview button to the comment quickreply

[foxfirefey]

There's a Dreamwidth patch I'd really, really love LJ to take up, and the community profile says contributions to LiveJournal code can be submitted here. It's adding a preview button to the quick reply comment box (more details here, including who made this beloved patch). I looked at the changes and they're pretty simple, so even if the patch doesn't apply cleanly (I think it will), it should be easy to recreate.

There's probably other little patches DW has that would be good for LJ to use--quick little things that might be nifty and won't take much work to apply. Should I look for more? Hearts.
