Changes to the admin methods

- cleaned up the methods, they all now return results without debug mode enabled
- Added a verification method for all user GPG keys (as an expired key for example would send out empty messages)
Threat level changes

- upgrade script that populates threat level from the old risk field for every event that doesn't have a threat level set.
- threat levels in an event (from a sync for example) that are unknown to the local instance now show the numeric value of the threat level
Changes to the sync action pages

- fixed access control
- any admin can now encode new servers. Org admins can pull/push for their own instances.

- Upload certificates during an edit
New permission

- tagger: a user that can create / edit / delete the list of tags that is usable for events
Tagging system

- new special role for tagging
- can create tags with a name + colour combination (using a colour picker plugin)
- users can assign tags to events
- can filter events by tags on the index
Fixes to the tagging

- made menu options invisible for non tagging permission users that requires the permission
- colour picker added to edit (was only enabled on add)
