Add handling of 437 (nick temporarily unavailable) errors
Servers bind a nick to a connection for a short window after it
disappears to try and avoid contention over nicks.  This may cause a 437
during connection to a server (c.f. ProgVal/Limnoria#1033) or even
during normal nick changes, if the timing is lucky.

Add handling for this error to the startup code and the Admin plugin.
