New SpaceReference displayer for wikimacro parameters

Hello all,

I’m working on implementing a new org.xwiki.model.reference.SpaceReference displayer for WikiMacro parameters.

The goal is to be able to easily set the value of wikimacro parameters expecting a space, using a dedicated picker.
Also, as there are no generic space picker, I’m also working on implementing one for this.

I created a jira ticket about it
I also started to create a design page for it.

If you have any feedback about it, I’d be glad to hear it :slight_smile:
