* Use autoloader for ConvertParser, and ExprParser which the code was cloned from * Fix PHP 5.1 compatibility, while there's no requirement for us to keep it, there's also no need to break it unnecessarily, and it's a really trivial fix in this case. * Tidy whitespace * Use ConvertDimension::getLocalisedName() for the dimensionmismatch error, as intended
