Web page changes

I've made a series of changes to try and organize the various webpages related to Greasemonkey.

• www.fixamotor.com is Greasemonkey's new home. It hosts this blog as well as links to download, userscripts.org, Dive into Greasemonkey, discussion groups, wiki, and dev site. greaseblog.blogspot.com now redirects here.
  
  
• wiki.greasespot.net now has a wiki that we can use for troubleshooting, etc. Thanks to Anthony Lieuallen for hosting this.
  
  
• greasemonkey.devjavu.com is the new home of Greasemonkey development, including source code.
  
  
• greasemonkey.mozdev.org is now archived and redirects here.
  
  

Have a look around and let me know what you think.
