Unify Prefix Labels

https://github.com/zazuko/rdf-mapping-dsl/blob/bda63d6d3eb6e42164ad09f69b00973311679a9f/runtime-EclipseXtext/airport-mapping/vocabularies.xrm#L2

Separating character ':' is used in the payload of Prefix.label in DSL-Files. This looks suspicous, since a separating character should be part of the tooling, not of the payload. For example see #34 , there only pure payload is meant to put in label. I propose to validate not having separators in the payload and implement them in the generators.

Implies changes in existing DSL files.

@mchlrch please check.

Yes, this needs harmonization. Prefix declarations should be uniform inside the DSL. Thanks for pointing this out.

Yes, let's change this as you propose.

That's fine. Validations will mark the places where changes are needed. Providing a quickfix would be nice, also for people that are used to turtle and maybe copy/paste prefix definitions from turtle files.

Tested and works. Nice that it comes with quickfix included
