Add a "Printable Version" link to Phortune invoices

Ref T9309. This is a minor quality of life improvement, hopefully. We already have print CSS, just expose it more clearly.

Also, hide actions (these never seem useful?) and footers from printable versions. I opened the printable version in a new window since it now doesn't have any actions.
