Make Redhen Paths respect the Admin Route settings

We didn't really catch all the routes here so re-opening with a fresh patch that includes entity paths.

The patch above could use some work: the entities each have their own submodule so we should probably have individual subscribers for each one.

Fixed in dev, commits didn't tag this issue. Will be in 2.1.0.

Automatically closed - issue fixed for 2 weeks with no activity.
