set nrepl-buffer-ns on load so C-c C-n isn't required before evaluation and meta-. work correctly.
Fix ido completion:
1) handle ns-refers in addition to interns
2) don't return a qualified symbol because the other nrepl-read-symbol-name options don't necessarily, and the qualification is wrong for refers
3) eval the callback in the buffer making the request so we can resolve unqualified symbols correctly
