When searching for 'st*ke', 'stryker' would incorrectly match, 'stryke' would
be added to the nick set and the subsequent lookup would cause a KeyError.
This is fixed both by anchoring the regexp ('^st.*ke$' instead of 'st.*ke')
and adding searchNick to the nick set instead of the string that matched the
pattern.

Also update commands.urlSnarfer to do the same, which allows us to revert
"Don't bother snarfing URLs from non-Action CTCP messages."
