Enabling the moderators_manage_categories_and_groups site setting will allow moderator users to create/manage groups.
* show New Group form to moderators
* Allow moderators to update groups and read logs, where appropriate
* Rename site setting from create -> manage
* improved tests
* Migration should rename old log entries
* Log group changes, even if those changes mean you can no longer see the group
* Slight reshuffle
* RouteTo /g if they no longer have permissions to view group
* This is to prevent user's timezones being changed accidentally
e.g. by admin looking at a user
* This problem only occurred via the user card, however the user card
was still calling userTimezone even if the setting to display user
time in card was disabled
Currently, when category or tag is muted, only after hard refresh, these new muted categories are really muted. Without a hard refresh, you will still receive "new topic" messages.
Therefore, when tag or category is muted, we should update the user object right away.
