Got a working PIT timer, so we can get interrupts at a regular choosable interval. That's nice for implementing a preemptive scheduler later.

Also I chose using the PIT instead of another timer (HPET/LAPIC..) because it's easier to implement and for now I don't care about multiprocessing.

When we eventually will want to support multiple processor cores, we will need to change this to use Local APICs (and ACPI Tables).
