- Fixed a bug where nowrap was causing table elements in classlist table to overflow
- Removed the buttons from the ProblemSets and ProblemSet pages
- Made the check boxes in a seperate column on ProblemSets, UserList2 and ProblemSetList2 so the text doesn't drop down
- Redid how select all/none works on ProblemSets2 and UserList2
Removing extraneous buttons and extraneous button coloration.
Cleaned up Instructor Tools page and Achievement Editor.
Removed abbreviations from course table
Fixed it so that the HmkwSetsEditor and ClasslistEditor tables have the same border.  (I had to remove a border attribute from the problem sets table, which really should be a css thing anyway.)
In the Hmwk Sets Editor I changed it so that _ turned into " " in the Set names.
Changed email addresses to "email" links in UserList2

-- I change the Email label to Email Link when we are showing a link to the email address
-- I think I finally figured out how to get the pencil icon to not drop down.
Changed some underscore2nbsp to underscore2sp so that spaces allow line breaks.
Removed underscores from ProblemSet page title because students see that a lot
