Working context switching but far from stable. Changes needed to be made to the internals of cosmos to include mutex's in vital components (Heap, Thread Manager, ect). Context switching currently only switches the general registers and does not switch the MMX context, however this will be added in the future. Also when a thread currently dies it takes the whole system down, patches to the IDT handlers needed to be made to prevent system lockup in the future
