A workable solution to network glitches and server restart events. Also added the correct multiplicity for featureWeightedGridStats.

This solution is not perfect, but gets the job done. This will catch any exception thrown during status checking up to ten times. I've also extended the status polling time to 10 seconds. The way we are "printing" for verbose is probablynot ideal, we need to discuss with the vistrails and Arc guys about how they want communication (or if they want communication).

The multiplicity changes are in response to a request by Colin. I didn't realize that wasn't in there already.
