Merge lp:~benji/charms/oneiric/buildbot-slave/who-needs-sleep into lp:~yellow/charms/oneiric/buildbot-slave/trunk

[Benji York]

This branch makes the test_master_slave_relationship test more resilient (removing a sleep) and much faster (by parallelizing unit startup.

I noticed that the (do_not_)test_script test won't run any more (it doesn't pass a required argument to .deploy()) so I removed it. It's safe in Bazaar's Bosom should we need to call upon it.
