BPMN.io UI For Setting a Json Schema for a Data Input / Data Output / Data Store

[danfunk]

For all Workflow Data (Data Objects/Inputs/Outputs) - allow specifying a json schema that is associated with these objects - embedding a reference to the file that contains the schema. It should be possible to author a new file or reference an existing file. Seems like an "up search" should be possible here to reuse Json Schemas, but also to save a file in the current process model.
