[misc] Massive improvements to process handling
...
- Free process resources when a process exits (reaped in next process
cycle; should probably reap after a wait() or something)
- Free process struct after wait()
- Fix page allocation
- Fix fork() return value for child process (attempted to write to an
invalid point in kernel-stack memory)
We shouldn't be triple faulting randomly anymore!
Continue investigating the fork() return value, as there was a bugged
return at some point during executon of a test run of thrash-process.

[text/io] Better text output management
...
- Fixes a number of bugs with VGA text-mode (including crashes and
colors)
- Makes it far easier to include more console drivers in the kernel,
though this will be terribly redundant in the future.
- Actually check for video graphics modes before attempting to draw the
mouse cursor.

[mem/task] Fix broken handling of page faults
...
The method I was using resulted in a loop of halts attempting
to remove process 0 from the thread queue if the kernel itself
was doing the faulting. This should fix that. Once there are
no more processes available, we bail out and call STOP.
