Non-option arguments to programs run using pbsdsh must be before --hpx:nodes, contrary to directions

[jewillco]

On http://stellar.cct.lsu.edu/files/hpx_0.9.5/html/hpx/tutorial/getting_started/unix_pbs.html, it states that the program's command line arguments should be placed after --hpx:nodes=.... If the program takes non-option arguments, however, they are treated as host names if passed in using that syntax. The correct solution is to have --hpx:nodes as the very last command line argument to the executable; it might be worth changing the directions to reflect that.

Jeremiah - excellent catch! I'll add some note to that effect to the docs.

I updated the docs (WIP) here: http://stellar.cct.lsu.edu/files/hpx_master/docs/html/index.html, reflecting my changes.
