* Add "test/literate/parameter-enabled-function-call-operators0.cpp" to test suite under alias 'parameter_literate_tests'.
* Add compose() test routine to "test/compose.cpp"
* Replace LIBS_PARAMETER_TEST_COMPILE_FAILURE_MSVC with LIBS_PARAMETER_TEST_COMPILE_FAILURE_VENDOR_SPECIFIC in case compilers other than MSVC start exhibiting errant behavior.
* Adjust for the fact that BOOST_PARAMETER_MAX_ARITY is defined regardless of whether or not BOOST_PARAMETER_HAS_PERFECT_FORWARDING is defined.
* Use minimal file headers to #include vice <boost/parameter.hpp>.
* Change test/evaluate_category.cpp and test/preprocessor_eval_category.cpp so that the tests pass for msvc-8.0, msvc-9.0, msvc-10.0, and msvc-11.0.
* Change test/Jamfile.v2 so that the compose_fail test runs only for msvc-11.0.
* Ensure that file permissions for header and source files do not include execute.
* Replace calls to boost::forward with calls to std::forward.
<boost/parameter/config.hpp>
* Relax perfect forwarding requirements so that msvc-12.0 passes muster.
<boost/parameter/parameters.hpp>
* Use boost::mpl::vector if neither boost::fusion::list nor boost::fusion::deque are true variadic MPL sequences.

* Remove test configurations of compilers that fail perfect forwarding requirements.
* Consolidate for fewer jobs.
1. The end of section 3.2.1 of the current home page tutorial notes "that because of the forwarding problem, parameter::parameters::operator() can't accept non-const rvalues." Add code to eliminate this problem. As a positive side effect, Boost.Parameter-enabled functions and constructors are no longer bound by BOOST_PARAMETER_MAX_ARITY on compilers that support perfect forwarding. User code can now check for this support by detecting the configuration macro BOOST_PARAMETER_HAS_PERFECT_FORWARDING, or manually turn off this support by defining the configuration macro BOOST_PARAMETER_DISABLE_PERFECT_FORWARDING. See "test/evaluate_category.cpp" and "test/preprocessor_eval_category.cpp" for example usage.
2. Add parameter category qualifiers "consume" and "move_from"(current qualifiers are "in", "out", "in_out", and "forward") based on http://www.modernescpp.com/index.php/c-core-guidelines-how-to-pass-function-parameters.
3. Update documentation to reflect the above changes.
