Converted thread states to BeOS equivalents (excluding THREAD_STATE_FREE_ON_RESCHED, which will probably go away once the slab allocator is in). Converted priorities to BeOS equivalents; we now have 60 priority queues to map the 120 BeOS priority levels (which have a granularity of 2, thanks Axel) plus the idle queue. Fixed PS.
