-------------------------
* Network.HTTP.Lucu.Resource: (Thanks: Voker57)

    - getPathInfo now un-escapes the resulting path info. This may
      break backward compatibility in very confusing way, if your code
      relies on the previous implementation. Sorry for any
      inconvenience.

* Network.HTTP.Lucu.Resource.Tree: (Thanks: Voker57)

    - Fix: mkResTree wasn't working correctly for a resource path
           [""], which should be treated as same as [] the root.

    - Fix: Greedy resources on the root of resource tree wasn't really
           greedy.

* Network.HTTP.Lucu.Resource.Tree:

    - New constant: emptyResource
