* heavily redesigned and improved the checking of attributes: instead of dying

  on the first error, we now collect all errors and return them. The caller can
  now decide what to do - die or just print a warning or whatever.
* slxconfig now dies with the list of all attribute problems if there were any
* slxconfig-demuxer prints warnings for all attribute problems that were found
  (checking for each system & client in turn)
* adjusted desktop plugin to API changes concerning the attribute checks
