Overhaullllllled the way we do streaming. There is an odd bug where

a zero length command (now, no chain) used to stop the streaming.
Now it seems to do the reverse... must investigate.

Made all clock configuration into enums. The strings were painful
and there cant be that many variations that enums cant cover them.
The enums will make more sense to developers than mystery strings.
