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.

A Follower is a generic model which indicates that a User is following
some other Linkable entity in the application.
Scope and scope_path should be set to the entity being followed.
The link_id should be used to indicate which user is following.
If more functionality is needed like for instance when following
either a public or private review for Student Proposals this model
should be extended. As to make it possible to create different types
of following.
