Adds to Melange a tags framework based on taggable-mixin.
The taggable-mixin allowed only tag per Datastore model. This is extended
framework allows any arbitrary number of tags per Datastore model. Also,
now one can define different models for different Tag types which are all
inherited from the base Tag model provided by taggable-mixin.
The GHOPTask model makes use of 2 tags per model, one for difficulty and the
other for task_type, both using the tags framework.

Documentation is items like tax forms, letters from schools confirming
enrollment, etc., (often scanned in) that are attached to a Role as
documentation related to that Role.
The specific way that some properties and relations inherited from Work
are used with a piece of Documentation are described below.
work.title: The title of the Documentation (e.g. "Verification
of Eligibility").
work.author: The author of the Work referred to by this
relation is the Administrator (or Host) creating the
Documentation.
work.reviews: Annotations to the Documentation made by other
Administrators.
work.content: Summary of the contents of the 'attachment', or
just an indication that the required documentation was
supplied but is not actually attached.
