Fixed mockup data to "new" URI Scheme. Also changed umlauts to actual umlaut-characters, as we will have them in "real-life"
Added global config. Moved addition of availableProperties to seperate function. Completed function isObjectProperty(). availableProperties are now stored in a Object rather than a Array.
Changed style of properties.
Added a custom filter which allows us to filter an array of objects based on a key and an array of allowed values for that key.
Added possibility to link object_datatype properties to an existing subject. Fixes: #9
Merge branch 'feature/improve-object-datatypes' into develop
