prevent some session deadlock errors.
* Fixed some bugs with the new auto-resizing toolbar:
* In IE 6/7, when you click on a formatting button such as italics, it
doesn't visibly depress, because update_toolbar() is causing it to
unpress until you start typing the italic text. Fixed by only calling
update_toolbar() in focused_editor() if focused_editor is null.
* When downing or upping a toolbar button, now calling
resize_toolbar_button() unconditionally.
* Added a fixed list of startup links.
* When link in list is clicked, open corresponding note editor.
* When a startup note is added/deleted, update the list.
Still much more work to do on this before it's complete.
made the header that's on the product pages present at the top of the wiki
page as well. Still need to make links bold when viewing certain pages
(help, contact, etc).
