Streamline virtual and hardware server listings.

The listing accrued too much stuff and was causing normal listing
to be way too wide. Additionally, masking in billing information
in order to get the creator of the server added a significant amount
of time to the API call.

FQDN column -> just display hostname (without domain name).
cores column -> removed
memory column -> removed
owner column -> removed

Now, only the following columns are shown:
 * id
 * datacenter
 * hostname
 * primary_ip
 * backend_ip
 * action (active transaction)
Uses globalIdentifier instead of id. Re-orders listing
Fixes style issues and incorrect test
Renames globalIdentifier column to guid

Fixes up images to satisfy #433 as well
Adds guid to vs/hardwate detail output. Splits FQDN
