(cannot use wildcards from within an ezjail-admin console command, doh!)
fix bootstrap (we need to use distribute)
use existing directory

(instead of creating yet another one)
bugfix: no need to pass in dir for console command
use the ssh config for connecting to hosts
fix typo in path to ssh key

add location for gpg et. al. to `$PATH`
