Bugout

Journal update content method returns list of tags and lock status.

Extended support of Brood applications for `users` and `journals`.

Web3 authorization support for `journals` and `get_user` handlers.

Properly handle network errors with no response object.

This update modifies `Bugout.update_entry_content` to accept tags as part of an entry update.

This means that users no longer have to make 2 separate HTTP requests to update an entry and its tags.

It also adds the `tags_action` parameter which takes values from the `bugout.journal.TagsAction` enumeration.

If `tags_action = TagsAction.merge`, the tags that the user passes to `Bugout.update_entry_content` are merged into the tags on the server. If `tags_action = TagsAction.replace`, they *replace* the tags on the server.

During token creation can be specified `token_note`.
