devel/py-simpleparse: turn mxBase dependency into option (default off)

- turn mxBase dependency into option (default off). It's only needed because of
  mx.DateTime and is not obligatory - f.e. pip didn't install it as dependency
- actualize comment and description
- bump PORTREVISION because of dependency change

+SimpleParse is a BSD-licensed Python package providing a simple and fast parser

+SimpleParse allows you to generate parsers directly from your EBNF grammar.
 
-Unlike most parser generators, SimpleParse generates single-pass parsers
-(there is no distinct tokenization stage), an approach taken from the
-predecessor project (mcf.pars) which attempted to create "autonomously parsing
-regex objects". The resulting parsers are not as generalized as those created
-by, for instance, the Earley algorithm, but they do tend to be useful for the
-parsing of computer file formats and the like (as distinct from natural
-language and similar "hard" parsing problems).

-reorganizes the code to allow for certain common EBNF constructs.
+As of version 2.1.0 the SimpleParse project includes a patched copy of the
+mxTextTools tagging library with the non-recursive rewrite of the core parsing
+loop.  This means that you will need to build the extension module to use
+SimpleParse, but the effect is to provide a uniform parsing platform where all
+of the features of a give SimpleParse version are always available.
