tools: Make pyboard.py have infinite timeout when running script.

Browse source 
This makes pyboard.py much more useful for long running scripts.  When
running a script via pyboard.py, it now waits until the script finishes,
with no timeout.  CTRL-C can be used to break out of the waiting if
needed.
