Feature request: change repo name in drone wall

[tallavi]

We use drone.io with a gitlab instance. Our repos are divided to a few groups, so the repo name itself is not very meaningful (for example 'core' repo in the group 'client').

I couldn't find a way to configure drone wall to show anything else for that repo other than 'core'. Not a way to add a full path including the groups ('client/core' instead of 'core'), and not a way to configure the name manually in the UI or in the drone.yml file.

It would be nice to have a yml key to set a name for how that repo should appear on the drone wall.
