TODO:
* Bookmarks of a location should remember that location (addr, company, etc)
CHANGELOG:
0.4 - 2005-06-19 - Bookmarks now save "link to this page" location,
got rid of lat/lon input box (can do this from main search
box). Fixed bug with GM @include directive.
0.3 - 2005-06-18 - Make sure we're using a GM_setValue compat GM for bookmarks
0.2 - 2005-06-18 - Bookmarks
0.1 - 2005-06-17 - initial release
