License is data!

This adds support for multiple, free form, licenses for each project. Project owners can use the repo name as a key and whatever license description as the value.

Looks like this:
```
license:
  repo: CC0
  repo: MIT
```
On the template side, each license is rendered alongside the other repo information with a link to the LICENSE file.
