Using the crab server or not: only for CRAB2

Comments and FAQ
- autocompletion with csh doesn't seem to work
- actually, is seems to work as intended
- TAB only completes unambigous prefixes
- use CTRL-D to list all possible matches
- as the old /user is not mounted, you will need to recreate the $HOME/.globus directory and copy your usercert.pem and userkey.pem files.
- don't forget to check the permissions of the files.
