Navigation plugin edit. Not using relative urls prevents plugin working for us

The Discourse Navigation plugin returns absolute urls rather than relative ones which means we can’t use it for navigation.

Example:
When clicking Tasks in the image above i want to visit:
https://publichappinessmovement.com/c/web-developers/rails/l/latest?board=default

instead i am taken to:

https://publichappinessmovement.com/latest?board=default

Discourse supports this as it works in other plugins and with the ‘latest’ tag. Please modify the plugin to allow users to choose between relative and absolute urls, so they can use it to navigate pages created by category or tag specific plugins and theme components
