Add build script (need boot2docker portion as well)
Rename file
Beginning of fix for infinite mirror bug

This introduces a fix which gets to bidirectional communication /
syncing at the cost of a global filesystem watch mutex.  The baby kind
of gets thrown out with the bathwater here, since any changes that are
made to the filesystem which are unreleated to the creation and
copying of the file to the other host also get lost in the aether with
the create event.  Will need to make the mutex file (and event type?)
specific instead of this temporary solution.
