Irc

=====

This release officially deprecates 2.0.1-2.0.3 in favor of 3.0.

* Re-release of irc 2.0 (without the changes from 2.0.1-2.0.3) for
correct compatibility indication.

===

* DelayedCommands now use the local time for calculating 'at' and 'due'
times. This will be more friendly for simple servers. Servers that expect
UTC times should either run in UTC or override DelayedCommand.now to
return an appropriate time object for 'now'. For example::

def startup_bot():
irc.client.DelayedCommand.now = irc.client.DelayedCommand.utcnow
...

===

* Added irc.client.PeriodicCommandFixedDelay. Schedule this command
to have a function executed at a specific time and then at periodic
intervals thereafter.

===

* Removed `irclib` and `ircbot` legacy modules.

===

* Fix file saving using dccreceive.py on Windows. Fixes Sourceforge 6.
* Created NickMask class from nm_to_* functions. Now if a source is
a NickMask, one can access the .nick, .host, and .user attributes.
* Use correct attribute for saved connect args. Fixes Sourceforge 16.

===

* Added ServerConnection.reconnect method. Fixes Sourceforge 13.
