GUI UPDATES Remove Empty Items on Cards

I'm going through several GUI updates and will be prefixing my patches with that name.
Addresses: http://www.projectpier.org/node/1216

On the company card and user card views all address/other information that is unkown no longer appears whatsoever. This means if there is no fax, a line saying Fax: n/a does NOT appear. Brought up in the above issue I agree with him but some may feel otherwise which is fine as this is purely asthetic.

The only disputable points I think may be if the box feels kind of empty perhaps leaving the title Address out of the if statement would suffice at least? Up to the reviewers
