* introduces new decorator "uuid_required" which performs a check on a given 'uuid' or 'id' parameter
* throws a Http404 exception --> redirect to 404 template instead of 500 error template
* simplifies geometries on SimpleGeomForm if threshold GEOM_MAX_VERTICES has been exceeded
* geometry is iteratively simplified to find a proper tolerance value which satisfies the GEOM_MAX_VERTICES threshold
* enhances visualization of editable column on tables
* simplifies code
* enhances visualization of parcel_group column on tables
* WIP: Ordering on intervention table is odd. Same results are being displayed on page 2. Needs further analysis and fixing!
