Updated jwiXML processor workbench.

My JavaScript/SaxonJS Invisible XML workbench 
(https://johnlumley.github.io/jwiXML.xhtml) has now been updated to 
version 1.5, with:

  * fixing of some edge-case bugs,
  * providing 'timeouts' to prevent explosive ambiguity runaways,
  * the addition of an experimental 'set-subtraction' operator
    (supporting concepts such as reserved keywords) and
  * the inclusion some very large auto-generated grammar examples
    describing XPath/XQuery 4 expressions.

(More details in the help pages.)

The corresponding iXML processor has also been improved, with some of 
the features above - a new version of this should be published on 
https://github.com/johnlumley/jwiXML in the next few days.
