Make screenshotter work with docker-machine (#494)

Browse Source 
Since boot2docker has been superseded by docker-machine, we need this to
support developers on OS X.  The changes to the bash script ensure that we
clean up our containers even if taking screenshots gets hung and requires a
keyboard interrupt, as happens if the IP addresses were guessed incorrectly.
