Assign colored stripes to favicons, based on URL and title regex matching.
This extension lets you target URLs and titles with a regex match pattern (so `.*\.local.*` for my local environment) and
apply effects to the favicon. I've got my local with a green stripe across the top, the staging server with a
yellow one, and could set different production environments with different colors and effects.
Another idea would be to match and apply effects for different signed-in Google accounts, so I'd know which
Google Drive is open.
