Fixed several bugs from previous commits (Bad distribution of changes across multiple commits).
Introduced striping of string fields before send back as replies in main.py.
Implemented POST and DELETE calls for /artnet/metadata/category
Implemented tests for the new calls.
URL parameters are now URL decoded by the webservice
The tests now URL encode the parameters for every request.
Art2Presence relations are now creatable with POST requests to /artnet/metadata/art and listing the presences in the body.
Art2Presence tests have been introduced with relate_art.py
Also updated column name artist.description artist.name to fit a db schema update.
Implemented a way to create, update and delete presences over the API.
Implemented code to list >ALL< artists similar to Art entries. Should be secured against requesting the entire database at some point.
Added debug prints to all API calls for clearer logging
