Add ability to control Link name display

[Aevaris]

Is your feature request related to a problem? Please describe.
When adding an external link to a model, it'd be nice if we could control its display. Right now it just shows hostname. I have a lot of pokemon STLs, and am linking them to bulbapedia. Would like to be able to control the name to show "PokemonName - Bulbapedia".

Describe the solution you'd like
It'd be neat to be able to use markdown, html, or wikimedia syntax to control link display.

Describe alternatives you've considered

Good idea. I've been thinking we do need more metadata on links, so this would fit right in.
