Enhancements for the eBird web interface

This browser extension comprises five independent enhancements or enhancement groups for eBird pages. The five enhancements are: * Identify flagged checklists * Trip Report enhancement group Sort checklists Copy checklist URLs to clipboard Download the set of GPS tracks Export trip report to spreadsheet * Checklist sharing * Download GPS track for one checklist * Download GPS tracks for all checklists See https://www.faintlake.com/eBird/extension/Enhancements/ for full details. Three of the four enhancements were previously distributed as separate extensions; now all are grouped together here and the old separate extensions can be uninstalled if you have them. You only need this one extension for all of the enhancements that I provide.
