IE6 Scroll Bar Patch

[Michael Cochrane]

Here's my solution to the IE6 scroll bar in the way issue. The patch defines a
quirk for this and in the common header include files it checks for this quick
and if it exists it defines a 25px right margin in the body tag so there is
space for the scrool bar if it is displayed.

Also I have patches for displaying a message number next to the message sumaries
and one to make use of scrollable message bodies in mozilla. Screen shots of
these are up and i will make diffs in the next few hours.
