initial 2to3 conversion for py3k support
Merge branch 'master' into py3k

Pulling in the latest master changes before I do much more conversion on the 3k
branch
last couple changes to get it working on py3k

One twisted module used is not completely finished porting, but the
function used is, so the import in plugincontroller is adjusted.

Changed "str" to "bytes" in irc.py, which should have been done by 2to3
but I guess it missed it.
added more verbose comments around 3rd party import errors

Also added a default config to the sneeze plugin so it doesn't just
crash with no config.
removed dep on py-pretty. updated readme

Readme updated with python3.3 dependency note and note about the
specific 3rd party modules needed.
readme changes

added a note on how to get the latest twisted

added a note about dependency on pyOpenSSL
changed a ' to a ’ in a line of wotd output
