Installation script for Cylc, Rose, and FCM

[dvalters]

To streamline installation + setup on Edinburgh systems.

Things this script should/could do before I forget on Monday:

• Check that the user has the correct PATHs and exports in their .bashrc file
• Check that .bash_profile or .profile are also set up correctly, since cylc global config use login shell defaults to True
• Check that user can ssh passworldless into the common servers on site
• Check for correct hostnames in known_hosts
• check or remind user to have a authorized_keys file in .ssh folder, to allow communication from job host back to suite server/host.

Dont forget FCM!
