WARNING: This check-in is in-between releases, is incomplete and doesn't work well. Use v1.0.3!

Started a major overhaul on how SSH is handled. Now uses the Net::SSH2 perl module and no longer requires host key, authorized_keys or other more complex SSH management.

So far, the main gather_node_details() function has been updated. Still have many other functions' ssh calls to rewrite still.
