Removed mob/var/UI, it now uses client.prefs.UI_style

Removed var/constant/Pi It's already defined in setup.dm
Moved a bunch of global_lists to global_lists.dm
Fixed hair randomisation. (still bits to do)
Moved a lot of preferences_setup.dm stuff into __HELPERS/mobs.dm They'll be FAR more helpful as generic procs, rather than something tied to preferences.
Merged mob/var/nopush into status_flags with the CANPUSH flag
Merged mob/var/nodamage into status_flags with the GODMODE flag
Removed mob/var/be_syndicate and mob/var/be_random_name as they are not used.
Added /proc/ui_style2icon(ui_style) proc. It converts a string like "Midnight" into its corresponding dmi file. The code fore creating a new hud uses it.
