Use unused stack space for variables #66

Without recursion, we can compute maximum call depth and estimate maximum stack 
use.
(We have to make reserve for interrupts and stack possibly used by assembler 
routines).

If the top of the stack is defined in processor file, we may just allocate 
adequate block of memory for it and leave the rest for variables.

Clever, 5oft's largest game so far (Special Forces) used max. 17 bytes of 
stack. High level code will use more but there are a lot of free bytes to use 
there. Next stop - casette tape buffer.
