Script Summary: Puts the menu back from the top to the left. Also sorts out the banner so it looks better. (Updated 28 May for new 'Applications' menu).
This script basically undoes some of the newer presentational layout changes for people like me who are afraid of change.
UPDATE (14-April-2007): Sorted out the dropdown menus, so I'm now happy with how they appear. Later in the day: Minor layout changes in code.
UPDATE (16-April-2007): Still playing with dropdown menus on the left. Now the lines aren't so spaced out in them.
UPDATE (17-April-2007): Menu bar down left now lines up perfectly. Login home screen now displays correctly.
UPDATE (19-April-2007): 'Profile' and 'Inbox' links now act the same as 'Friends' and 'Networks' links on mouseover. Changes written to do this for the links below these, but commented out. It's around line 135 for anyone who wants to remove the commenting.
UPDATE (28-May-2007): New 'Applications' item on the left now changed to appear like the other items on the left. Screenshot updated.
UPDATE (29-May-2007):Edit links now a darker grey, small changes to commented out code.
UPDATE (18-June-2007):Menu on left now expanded the whole time.

UPDATE (24-April-2008):Minor tweaking due to style changes on facebook.
UPDATE (14-May-2008):Small fix due to another facebook change. Still not 100%, but maybe around 80.
