Update Notification Refactor (#511)

* Replaced profile links to anchors so we can open in new tab if we like

* Refactored how update checking works. We now explicitly check and send back on the same API. We have a weekly job that will push an update to the user.

* Implemented a changelog tab

* Ported over a GA fix for using ' in PR bodies.

* Don't check cert for Github
