Link detection for title, location, and description

Websites, email addresses, phone numbers, etc., are now auto-linked in any fields in the right-hand context panel. This is especially useful to have one-click access to Zoom meeting links that often get pasted in the location field. In addition, Cron will launch the native Zoom app directly if installed without opening a browser tab first.

When editing one of the fields, holding down ⌘ turns the text editing i-beam mouse cursor into a hand when hovering a link to follow it even when editing links and surrounding text.
