* Remove last admin check for removeUserFromRoom

* Move and fix last admin check for role removal

Check was on change admin status method, but that didn’t catch direct removal of user from role admin view.

* Fix last admin check for insert/update/delete user

Was checking if only one admin but not if the updated user was admin, preventing all updates.

* Allow translation of last admin error

* Fix assigning admin permission bypass

* add beforeSaveMessage callback to check if a user has the appropriate permissions to notify @all in a channel

* add settings to toggle 'allow notify @all' feature

* cleanup

* cleanup of coffeescript habbits

* implement the filter for @all using `mention-all` permission

* add user by default to the list of roles of the `mention-all` permission

A new permission is added 'manage-own-integrations'.

    The new permission, if present without 'manage-integrations', grants
    the user access to add integrations, but only to view, modify or delete their own.

    This permission is given to the 'bot' role , which has 'manage-integrations'
    removed from it.

    This closes #2900.
