Fixed small bug when stopping the scheduler; re-enabled the test (after leaving it more time to execute).

Improved behavior of 'jman ls' and 'jman del' commands; added more informative output during scheduler run.

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).

Added a job manager that executes jobs in parallel on the local machine; use jman -l to enable; This feature is still under development and might be buggy.

'jman refresh' now also ignores 'INFO' messages (as generated from the SGE) when --ignore-warnings is enabled.

Made database handling more safe -> allow parallel database access by changing the type of database that is written (old databases are still readable); jman ls will now sort the jobs according to their ID.

Fixed logger that was not working with python 2.7; added sphinx builder 'bin/sphinx' and cleaned up docs directory; changed version$

Corrected small bug in the grid script; changed names of q... executables to q....py to not overwrite the default programs.

Added possibility to query dependencies between jobs; Now, the job_manager can also be used inside the grid; fixed some small issues.

Added option to ignore warnings while refreshing (jman refresh --ignore-warnings); added 'job-name' to the list that is shown on 'jman ls'.
