* formerly vmchooser_env in vmchooser.conf
* pool/vmchooser_env in vmchooser.conf
* -P/--pools command line option
* a virtual session will only be displayed if
  a) their pools attribute contains pool
  b) their pools attribute is unset/empty
  c) pool is unset/empty

* fix for segfault with invalid command line options
