Added employee number to asset view

[snipe]

This went a little out of scope, but I think the changes are good. As we continue to build out the visual lexicon, I think these changes will matter.

The initial change was just to add the employee ID to the asset "checked out to" section.

In the future, I might make this a popout menu or user card to save space, but I'm okay with the solution I have here for now.

Note I did not include the glyph if it's checked out to user, since the gravatar() method already handles that.
