* added support for os-plugins:

  + added script slxos-plugin, which must be invoked to install a plugin into
    a vendor-OS
  + added handling of plugins to slxconfig-demuxer
  + added folder structure for plugins (below 'os-plugins')
  + implemented one simple plugin, called 'Example' which contains a couple
    of hints how to write own plugins
