Minor fixes to the tensioner, changes to the borg deathsquad from 6->3 and fixes their cell

Changes changling unstun time to 45 from 25
Fix for the datumvars file which had spaces instead of tabs
Adds the starts of a rather robust erping system!  In time, we can make SS13 as realistic an ERP simulator as it is an atmos one.
Adds metadata support for clients, mostly to hold ERPing notes.  This is included in the savefile.
Adds code support for a parrot in!  Just needs a sprite
Bugfix to the 'resist' button, unless I don't understand how it works.  I don't see how it could have ever worked before.
Preferences are now attached to a mob
