Ed Bartosh e85f807b87 wic: use optparse instead of cmdln
cmdln.py https://pypi.python.org/pypi/cmdln was used in
creator.py to parse image plugin options and arguments.

There is no need in such a sofisticated API to do this
simple task. Standard option parser optparse.OptionParser
can do it just fine.

Modified Creator class to work with option parser.
Removed cmdln.py from the wic codebase.
