Merge pull request #333 from joshvillbrandt/develop

Fix sorting with ?version=diffs
Rename defaults_value.py to defaults.py

Will hopefully cause less confusion since we also have
defaults_settings.py in the same folder. Moving the file to the methods
folder (as discussed in #327) didn't seem appropriate as the module is
being used in the flaskapp module too.
HATEOAS links as business unit values.

HATOEAS link for the item and resource espresses the business unit value
even when regexes are configured for the resource endpoint. This applies
to resource and item endpoints. Home links are still showing
the regexes (as they are not computable based on the current request).
To address these I plan to add a filter/parser in the near future.
Delete orphaned function
Add py34 to tox envlist
