021585e9ef [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.

5d0f3f0f3d [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.
