PHP version number in composer.json

Changed PHP version number in composer.json from fixed value 5.3.18
to range >=5.3.18,<6.0.0
This allows composer, grunt etc to run with the latest versions of
XAMPP which include PHP version 5.4.x
Limited compatibility to 5.x.x in case PHP 6.0 changes something
dramatically.
