Changes

tsk19 (Fix) Changes how story views are registered
Adds entity View, with its tests, that tracks when each view was created
and updates sql script for automatic data insertion after deployment. It
changes how REST sends stories, using a DTO instead of a Story, in order
to prevent LazyInitializationException when retrieving data. Finally, it
updates all tests and datasets, add its required matchers, so they keep
working after the entity changes.
