Add module editing on mobile

[mattco98]

Module editing should be possible from mobile, excluding releases of course. The first idea about how to implement this would be an edit button on the module page itself. When pressed, all of the editable parts of the page (image, description, and tags) would become input fields, allowing the user to change them. Where ever the edit button is initially placed, a "Done" and "Cancel" button should take it's place while editing.

This requires the markdown viewer to be modified to look good on mobile, controls and all. This would be quite a challenge, and isn't super important, as most people aren't going to be editing their modules from their phone. Maybe after release, but not before.
