Support for Sun Grid Engine (aka. N1 Grid Engine) in Gateway

Attached is a script to add support for SGE (Sun Grid Engine) queuing system. The script must be installed at /MaterialStudio//Gateway/root_default/dsd/commands/queues/SGE and specify "SGE/dsd_sge" as queuingsystem. The script has some hardcode SGE_ROOT, SGE_CELL, and SGE_QMASTER in dsd_sge.pm that need to be fixed to appropriate directory. The script is created on ROCKS cluster 4.2.1 so it should works fine with any ROCKS cluster 4.2 or above.

Please note that, the script use SGE supplied machines file, not the default share/data/machines.LINUX in MaterialStudio.
