Fixes and Tweaks as of October 24, 2009

I sneaked a few fixes to the application, based on these posts in our GetSatisfaction.com page:

1. Fixed problem when changing Plurk accounts
2. Removed default qualifier "says", since Plurk automatically extracts valid qualifiers from the message when no qualifier is specified

If you have any more questions or concerns, feel free to post them in our GetSatisfaction.com page!
