Initial LAPIC initialization (mostly just for the APIC timer)
Had a bug in the queue code......
New scheduler with sleep support (still a WIP, but appears to work)
Added information for sleeping
Removed the PIC code because it's no longer used, the LAPIC is
Imports from the LAPIC timer
Will probably re-add explicit timer initialization later
Added sleep support
Added the msleep syscall
Program to test msleep/fork
