Added support for a wider range of operators (mathematical unicode operators)
Changed the internal API for Object::VARIABLE; now it calls get_constant('VARIABLE') instead of get_const('VARIABLE');
Added a special case for perl 5.14.4; all user-defined methods must be UTF-8 decoded (because $AUTOLOAD holdes an UTF-8 encoded string, which perl-5.14.4 seems to encode it once again before using it)
