remove leftover console.trace()
Add DEBUG_STORAGE flag.  Simplify storage.settings, make each setting its own storage key.
Ignore a few more messages when it comes to console.logging them.  Remove unnecessary test for TowTruck.startup._launch in startup code
update peer on bye message.  Fix bye message handler.
Hide cursor on peer bye
Fix some cases of .once - name clashes changes to the handlers while processing handlers.  Add the styles even when TowTruck() doesn't load TowTruck (like in tests).  Put in argument checking in .on/.once.
Add some more testing, including a cleaner functional test with only a fake remote peer.
