You can now have multiple -t and -n switches.

*** This change requires you to re-run 'bundle' to get the latest ejt_command_line gem ***

The -t switches are ORd together to make one filter.  Similarly the
-n's ORd to make another.  These two are then ANDd to make the final
filter.

eg,

root@debian:~/dmtest# dmtest list --suite thin-provisioning -t /Fake/ -t /Basic/ -n /device\|pass/
