Added draw menu, vars and additional functions needed for it

Browse Source 
Added some functionality to the procdump to show the current console and parent pids of processes for debugging
Added var to clearconsole that enables the internal lock if one wasnt prelocked before hand
Fixed issue where race conditions would stop the title from drawing by drawing it to the buffer too
Fixed issue where the maze function was spamming the conswrite and cons lock by changing it to send an entire line instead of 1 char at a time
