debug.pl -- Set options for development

This module make ClioPatria more suitable for development. In particular, it implements the following methods:

• Load library(http/http_error), which causes uncaught Prolog exceptions to produce an HTML page holding a stack-trace.
• Load library(semweb/rdf_portray), which prints RDF resources in a more compact way.
• Load library(semweb/rdf_db) into the module user. This allows usage of rdf/3, rdf_load/1, etc. from the toplevel without specifying the module.
• Use debug/1 on the topic http(request), which causes the toplevel to print basic information on the HTTP requests processed. Using copy/paste of the HTTP path, one can assemble a command that edits the implementation of a page.

  ?- edit('/http/path/to/handler').

• Define tmon/0 that brings up a graphical tool showing thread activity.
