Maya 6.8-0 Jobtype

This release is designed to work with Qube! version 6.8-x.

==== CL 14609 ====
@CHANGE: adjusted code to reflect unexpected/undocumented change in arguments to a v-ray routine (in vrayDR.mel), vraySaveServersInfo(), provided by Chaos Group.

New code should still provide backwards compatibility for v-ray 2.x.

==== CL 14347 ====
@FIX: set MAYA_DISABLE_CIP env var to 1, to disable "customer involvement program" feature, to work around Maya 2016 jobs on Linux crashing at launch.

@FIX: add code for vray renders to respect "File Name Prefix" override.

Apparently, vray has its own setting, "vraySettings.fileNamePrefix", and
doesn't respect Maya's "defaultRenderGlobals.imageFilePrefix" setting.
