Title: Support for arguments that are dictionaries

When using arguments such as ```param[first_name]=travis¶m[last_name]=beauvais``` that is currently considered 2 different arguments. You would need to access them like ```self.get_argument('param[first_name]')```. It should be a single argument that is a dictionary. ```self.get_argument('param')``` should return ```{'first_name': 'travis', 'last_name': 'beauvais'}````.
