Added auto-generated appendix with list of SHACL syntax rules

I have formalized the syntax rules in the body of the text using HTML 
<span data-syntax-rule="..."> elements and there is now an Appendix that 
lists all these rules, populated via JavaScript.

This approach keeps the flow of the document "natural" while addressing 
the needs of those who are primarily interested in a list of the precise 
rules. The rules are formulated into individual clauses most of which 
can easily be converted into SHACL Shapes.

     http://w3c.github.io/data-shapes/shacl/#syntax-rules

Note that violation of these rules merely means "result of validation is 
undefined" - we can impossibly require this kind of meta-checking before 
each individual validation.

Cheers,
Holger
