Read environment specific options

* Vmchooser reads from $vmchooser_etc_path/vmchooser-$pool.xml and merges its
  contents to any virtual session .xml file
* file format:

<environment param="$pool">
  <printers>
    <printer path="..." name="...">Some Printer</printer>
  </printers>
  <scanners>...</scanners>
  <shared_folders>...</shared_folders>
</environment>
