sview scalablity patch

Scalability problem with SView when there are lot of jobs running and more jobs queued.  We made an improvement related to the memory allocation done when  building the data structures.  We defined a configurable node limit to allocate at a given time.  Then as the window slides, the widget loads a different set of 1000 nodes.  We were only able simulate a large number of nodes.  But it seems to be working quite well.  This work was done by Doug Parisek

scalability for sview

The attached patch appears to increase the speed under heavy load on all tabs.  Let me know if this does not work for you.  This will be in 13.12, but this patch is probably able to work on 2.5 or 2.6.

If you think things could be improved more than I have already done please reopen.
