* Allow running mastodon on a different domain as the one used for identifying users

* Alter documentation of WEB_DOMAIN to make clear it shouldn't be used unless the admin knows what they are doing

* Compare to web_domain instead of local_domain when dealing with feeds/API

* Correctly identify mentions to local accounts

Mentions URLs point to the person's web profile, i.e., the user page served on WEB_DOMAIN.

* Add exclude_types param to /api/v1/notifications

* Exclude notification types in web UI through exclude_types in the API

* Allow users to update their Account in the API

It would be nice for API clients to be able to allow users to update
their accounts without having to wrap Mastodon in a web view. This patch
adds an API endpoint to let users submit a PATCH for their account.
