Show version in panel

[ollyhensby]

Problem

Would love to be able to show the version of the application e.g.

Excuse the terrible screenshot but you get the idea.

Currently we just put it within the name.

Proposed Solution

Add to the gallery.html a div to show the version if passed (with appropriate styling). I am not sure where is best to show it but maybe its in a rather small font and shown in the bottom right of the panel.
