The connect() method already adds it, so it was in the list twice
(added both by __init__() and connect()).
This caused _select() to call _read() twice on the same instance,
except there is usually nothing to read on the second call,
so it blocks for up to conf.supybot.drivers.poll().
Fixes c1d3bad64f, which crashed with:

To prevent infinite recursion on startup, because defaultHttpHeaders
gets the value; which is unset, so 'registry._lastModified > self._lastModified'
is True, so .set() is called, so .setValue() is called again.
This requires commit b54d8f8073, which separates the timeout and no match cases.
Also, raise the default processTimeout as the plugin now aborts on the first message that times out.

Some IRCds (Unreal 3.2) don't mangle target names for case correctness, leading to a bug where users end up ignored by the plugin.

Although the default has been adequate on my systems, busy or low-powered machines may fail to process regexps quickly enough and cause SedRegex to sporadically error.

The 'receivedBy' tag is now checked to match the current IRC object, which Works around ProgVal/Limnoria#1211.
