4de121142b Adds a flags parameter to the BestEffortUpdater delegate. 
On the Cocoa side, cuts Swift out of the update loop, as that seems merely to add code.

cb61e84868 Starts building out higher-level run_until functionality. 
Specifically: you can now run until the next set of speaker samples has been delivered.

8349005c4b Adds CRTMachine::run_until, which will run until a condition is true. 
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.

5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.
