Subclasses have their superclass as part of their namespace and objects in the
subclass's namespace must be registered first.
Reverse the list of parsed objects so
that the classes will be handled and registered in the correct order.
Due to the changes in PUP-3900 which renamed Puppetx to PuppetX
and puppetx to puppet_x, strings was failing since the namespace
had not been updated in strings. In order to be compatible with this
change, update strings by renaming the namespace to match.
In order to ensure strings is still compatible with earlier versions
of puppet that don't include the namespace change, declare our own
PuppetX module. This way, if it is an older version and the namespace
is called Puppetx, the necessary PuppetX namespace will be created.
