implemented plugin dependency handling:

* installing a plugin into a vendor-OS is now only possible when required 
  plugins are already installed
* removing a plugin from a vendor-OS is now only possible when now plugins
  that depend on this one are still installed
* the config-demuxer will check the plugin depedency hierarchy and bail if 
  any plugin is missing
* when several plugins are being auto-installed (e.g. when copying all
  plugins from the '<<<default>>>' vendor-OS) the order of the plugins is
  adjusted to comply with the dependency hierarchy
* declared one single dependency: vmchooser depends on vmware (please shout
  if that is incorrect)
