Greasemonkey script to fix problems with new Yahoo! Groups

The new Yahoo! Groups is awful. Since Yahoo! doesn't seem to be in the
habit of fixing it, and since they keep deleting my bug reports
(wtf?), I've taken it upon myself to be proactive and make a
Greasemonkey script that fixes some of the damage. You can find that
here:

Here's a list of functionality that it restores:

1.It restores the "Fixed Width" function by adding a button for it
below the message-header toolbar. It also sets to fixed-width by
default if ?var=0 is appended to the end of the URL, like the old
days.

2. It causes visited links to appear a different color than
non-visited ones. This seems to be the intended behavior, but a CSS
specificity bug caused links to always be the same color no matter
what.

3. It auto-unhides quoted text, as the auto-hider is broken and often
hides everything.

4. It changes the "Search Groups" button to say "Search Messages" when
you're actually in a group, making it clearer what that button is
supposed to do. Note that this doesn't change the functionality of
that button, just gives it a better label.

5. It clearly indicates that the new "Conversations" section is the
same as the old "Messages" section.

6. It adds a tooltip if you hover over "Topics," letting you know that
this is a list of thread-titles only.

7. It clearly articulates that the "Messages" section is for
"Individual Messages."

So far I've tested it on Chrome 29 (using Tampermonkey) and Firefox 23
and 24 on Windows Vista (lulz) and there haven't been any problems. If
people want to give it a shot for other browsers, let me know what
works and I'll add it to the list of stuff that's supported.

Also, if anyone has any other features they want added, if they're
simple enough, I'll take a gander at it.

Cheers,
Mike
