Small error in mult_search.com

Hi everyone,

I was using frealign on our cluster this weekend and noticed that there is a small error in the submission lines for PBS clusters in "mult_search.com". Lines 217 and 219 both reference the mult_(h)refine_n.com scripts which terminates the search without producing any output. After changing both lines to the mult_(h)search_n.com scripts, everything works as expected. Maybe this change can be made in a future releases of frealign.

Best,
Thomas
