Add a button to export When2Meet availability data as CSV
If you have a when2meet survey, sometimes you might want the per-person availability data to do fancier scheduling (e.g. to figure out two or more meetings that cover everyone). This simple script gives you an "Export CSV" button in the bottom right to export that raw CSV data. It comes from JavaScript global vars on when2meet, and will respect the currently selected timezone on the site.
