Add repository link to Marketplace

[unikitty37]

There is no link to this repository in the Marketplace entry:

I had to go to https://amod.io, click on the GitHub icon at the bottom of the page, and search through the repository list to find this. Would it be possible to add the direct link to the Marketplace entry, to save people the hassle?

(And yes, I have only now just noticed there's a link to the issues page in the actual README pane to the left 😊 That's not where people expect to find the repo link, though…)
