--TODOS:
--DR timers
--fix config for drs, add in displaying the number of drs, add in a config -> where to show them uncomment enableds
--fix libdrdata, its dr groups are bad
--spec detection
--Way to show pet cds on the master -> currently looks impossible
--add every version for arcane torrent (BE racial)
