Improve the runspoke.py tool and make it callable from make

make runspoke SPOKE_MODULE=source

or

make runspoke SPOKE_MODULE=source SPOKE_CLASS=InstallSource

- runspoke now accepts the name of the module containing
  the spoke the user wants to run on command line and
  will find the spoke automatically

- as an optional second argument, the script accepts the
  name of the spoke class

- install classes and gi introspection files are looked for
  in anaconda sources first, so there is no need to install
  the anaconda-widgets package to the system

- anaconda should use ANACONDA_DATA, ANACONDA_WIDGETS_DATA and
  ANACONDA_INSTALL_CLASSES env variables to look for data files
  if those variables are defined

- there was a circular dependency between yuminstall,
  backend and kickstart modules, which caused import yuminstall
  to fail, because:

  yuminstall called backend, which called kickstart, which
  requested NoSuchGroup from yuminstall. NoSuchGroup was
  present in the source, but much later, so it hadn't been
  evaluated yet and the import failed with missing symbol error.
