Kernel: Expose per-thread information in /proc/all

Browse source 
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.

SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.

Fixes #66.
