* don't allow streams to have <section> labels
* update the <auto> algorithm to allow stream pointers to be picked up in the middle of a script. This will get changed if the script is recompiled to put the streams at the end, but it allows longer scripts to be read no matter where the streams were placed.
* better for experts because they can more easily parse a handful of section headers compared to random hex addresses
* Better for new users because it helps them learn that they can use whatever names they want for the headers of scripts and for pointers.
if the last thing is a label, make sure to include an end command for it
if the last thing isn't an end command (or goto, etc) make sure to include an end command for it
