sstat and updated man page

to become effective.

    MinJobAge configuration parameter. Small values for MinJobAge should improve
    responsiveness for high job throughput.

    sockets_per_node, min_cores to cores_per_socket, and min_threads to
    threads_per_core (the values are not minimum, but represent the target
    values).

    The default MaxJobCount was changed from 5,000 to 10,000.

    initiation will be delayed until all allocated nodes have booted. Salloc
    will log the delay with the messages "Waiting for nodes to boot" and "Nodes
    are ready for use". 

Patch for adding CR_CORE_DEFAULT_DIST_BLOCK as a select option to layout jobs using block layout across cores within each node instead of cyclic which was previously the default.

    (currrently in the contribs directory, but plan to distribute through
    http://code.google.com/p/slurm-spank-plugins/).

    Useful for batch jobs (in Prolog or the script) if powering down idle nodes.

    wait for all allocated nodes to power up before proceeding. Salloc will
    log the delay with the messages "Waiting for nodes to boot" and "Nodes are
    ready for use". Srun will generate the same messages only if the --verbose
    option is used.

Fixed a couple of problems for NO_CONF_HASH too (bits were 0x12, changed
to 0x20, added documentation to slurm.conf man page, and add logging for
scontrol show config).
