Geocaching Waypoint Finder - v1.6 2010-06-02
(c) 2010, Prime Suspect Software

Greasemonkey user script: see http://greasemonkey.mozdev.org

Compatible with Greasemonkey 0.6.4.

This script adds a waypoint/travel bug ID search box to the left 
hand menu on every page of the geocaching.com website. Home page 
and search pages are excluded, as they already have a search box.

Change Log:

* (v1.6) 2010-06-02 Update for site changes. Added auto update 
	notification.

* (v1.5) 2010-01-15 Update for site changes.

* (v1.4) 2009-01-26 Travel bug owners no longer need to enter the
	tracking number when posting to their own bugs.

* (v1.3) 2008-12-02 Added support for Tracking ID entry. When a
	tracking ID is entered, it will automatically be passed to the
	logging page, removing the need to enter it twice.

* (v1.2) 2008-08-14 Minor fix to accomodate website changes.

* (v1.1) 2007-10-10 Minor fix to accomodate website changes.

* (v1.0) Initial release.
