Michael Krasnyk dac2f93383 Refactoring of parameter garammars
* signature changed from void() to void(engine::api::Parameters&)
* performance increase due to use "static const GrammarT" and avoid
  construction and destruction of grammars during parsing
* removed code duplication in inherited grammars
* rule unlimited changed to qi::lit
* added rule size_t_
* parser accepts "&geometries=" and "&overview=" and fails at "foo"
  instead of "&geometries=foo" and &overview=foo
* added expectations checks for derived grammars
* changed rules qi::list(".") to character rules '.'
