Allow 'message' predicate to take a regular expression as argument

This change adds RegEx support to the existing 'message' predicate.
The primary intention is for this to be used in submit requirements,
but since some index backends (e.g. Lucene) support regular expressions,
we add it as index predicate.

The matching is the same as for other index predicates
(e.g. RegexDirectoryPredicate) using brics.dk/automaton. This is a
notable difference to Prolog (which uses Java's built in Pattern).

Documentation was adapted.
