Creates views in the database for easy displaying of damage data in QGIS

Currently, somewhat complex queries are needed to display the damage state of tiles and buildings, e.g.:

SELECT geom, quadkey, osm_id, district_id, damage_probability, occupancy from Entity
inner join DamageAssessment on DamageAssessment.entity_id = Entity.id
inner join Damage on DamageAssessment.id = Damage.assessment_id
inner join District on Entity.district_id = District_id
where Entity.osm_id IS NULL
and damage_state_id = 2

Database views need to be added to allow for easy drag and drop into QGIS.
