4008 Links in login block squished

https://code.google.com/p/otwarchive/issues/detail?id=4008

The "Forgot password?" and "Get Invite" (or "Sign Up", when invitations are disabled) links in the log in form in the header didn't have a space between them. I've unsquished them, and also moved them out of the form element, since they had no business being there.
