Add get_all_networks() to return both public and private networks for the current session
Pull vagrant gem over https, as the git protocol may be blocked from some networks.  Add plugins group so bundler will use the local copy of the plugin, this is covered in the plugin developer docs and seems to be necessary for newer versions of vagrant
Add rspec test for listing all networks, and add support for arguments to the network_list command
Add argument verification to network-list and return error if unrecognized
Remove errant whitespace.  Forgot to rake before pushing to github :(
Merge pull request #113 from smo921/public_networks
