// @name          Modify GCal Reminder Times
// @namespace     http*://www.google.com/calendar/render*
// @description	  gives more options for reminder times
// @include       http*://www.google.com/calendar/render*
// ==/UserScript==
// Notes:  Modifies the reminder times for Google Calendar Events.  Click on an event, click Edit Event Details,
//	Edit the script to change the available options.  
//	I feel that the default settings, with a gap between 3 hours and 1 day, are lame.   :)
//	Note that this script DOES NOT read reminder times that are not in the overlapping set of default reminder times
//	and times in the script, so if you set an event time with this, then re-open the event, it may not display correctly
//	in the drop down box - but it will be stored in your calendar correctly, unless you save the event again.  
//	Anybody that understands the gcal API wanna fix this?
//	--Rockmaster
//
//   update 2006Nov10 - removed extra "selected" form tags, added 18 hours option.
