Log Message:
Add py-yamlordereddictloader version 0.4.0.

This module provide a loader and a dumper for PyYAML allowing to
keep items order when loading a file (by putting them in OrderedDict
objects) and to manage OrderedDict objects when dumping to a file.

This is apparently subsumed by
  https://github.com/Phynix/yamlloader
but is for the time required by the coming py-junos-eznc update.
