Fixed bug in resubmission of jobs with no dependencies (which finally were dependent on all jobs of the database).

Implemented resubmission of jobs to another queue; enabled jman's --job-ids parameter to be more sophisticated; listed command line is now wrapped with '' e.g. to allow directories with spaces; local jobs can now be run with priority; added warning when queue combination is not valid (and jobs will never execute); fixed small bugs.

Added possibility to use Idiaps multi-thread queues; Added a '--long' option for jman list; Fixed bugs in re-submitting jobs.

Added support for --stop-on-failure option; bug fixes in the local scheduler; updated documentation; small improvements.

Added functionality to re-submit jobs; some bug fixes; added first unit test (so far it tests local execution only).
