VERB 24 and 25 Support

[b-wave]

For V24 and V25 to work, the Task List must be working. In other words, to do a V24, we must issue V21 and V22 as secondary tasks to load all the registers. V25 needs V21, V22, and V23 tasks to run.

WAITLIST Will work like this: Need three variables:
TASK db 1 ; Byte holds current task index
VERB db 3 ; 3 locations for 3 deep tasks (assiming 16 may be running in task 0)
NOUN db 3 ; 3 locations for associated NOUNS

to store new tasks the list grows 0 -> 3
to execute task, check from tail of queue 3 -> 0

As the task completes the TASK gets decremented and the VERB, NOUN clear.
