Ralph Castain 18cb5c9762 Complete modifications for failed-to-start of applications. Modifications for failed-to-start of orteds coming next. 
This completes the minor changes required to the PLS components. Basically, there is a small change required to the parameter list of the orted cmd functions. I caught and did it for xcpu and poe, in addition to the components listed in my email - so I think that only leaves xgrid unconverted.

The orted fail-to-start mods will also make changes in the PLS components, but those can be localized so they come in one at a time.

This commit was SVN r14499.
