2.2.0 - Built in Extension Overhaul

• Fixed the annoying bug where the uBlock Origin extension was missing an icon and was messing with the scroll
• Built in extensions now also get extracted to the extensions folder for easy customization
• The built in extensions got ripped out of git submodules so now they can be updated more cleanly
• In particular the agregore-history extension now has it's own repo
• Adding a new extension just requires linking to a URL for a zip file along with the expected version in the manifest file (following semver)
• Optimized the initial load time, there should be a few noticible seconds of improvement due to reshuffling the order of operations for protocol registration
• More verbose logs for the initial load so you can know what's going on under the hood
• JSON renderer extension now properly handles JSON-LD and ActivityStream pages
