Updated proposal to close ISSUE-51 based on Turtle file in ISSUE-51 branch

Dimitris and I had some detailed discussions about ISSUE-51 and I 
believe we have largely agreed on a revised design that I would like to 
propose to the group:

PROPOSAL: Close ISSUE-51 based on the design outlined in the Turtle file 
https://github.com/w3c/data-shapes/blob/ISSUE-51/shacl/shacl.shacl.ttl

Note that I did *not* yet update the textual companion documents because 
this would be quite some work that I'd rather delay until we have a 
general agreement.

Summary of changes:

There are now three kinds of results:
- ValidationResults point at a severity level such as Warning and Error 
and provide additional details about which triples were causing the 
violation
- FailureResults are unexpected situations such as unsupported recursion 
or communication problems with a database ("sorry we could not process 
your request")
- SuccessResults can be used to capture successful runs, for logging 
purposes

It is easy to add new types of severity levels (which also carry an 
index so that they can be ordered), and failure types. The design also 
makes it easy to repurpose the severity levels for additional use cases 
such as accumulated results.

There were also various renamings and other minor clean ups. Nothing 
changes for the syntax of the SELECT queries.
