New static handling

Slightly modifies hendrix's HendrixService to allow NamedResources to have a method "get_resources".  

*get_resources* is implemented on a **contrib.resources.static.DjangoStaticsFinder** class which finds all static file directories through Django's built in methods and returns a normal NamedResource for each.

The end result:  Static files are now served from app directories and other custom static locations with no additional configuration other than adding 'hendrix.contrib.resources.static.DjangoStaticsFinder' to HENDRIX_CHILD_RESOURCES in settings.py
