Support of polymorph app added

1. Support of polymorph linux filename convertor added - see the branch
if appName[0] == "polymorph":

substring "D*...", where * is some non-Ascii character, will always be in the output in case of successful attack. Also, there must be no "Segmentation fault (core dump)" message in the output. Messages "polymorph had trouble converting", "the file is now possibly corrupt" appear if filename was not converted by polymorph i.e. because the filename is wrong and file does not exist

2. sleep(1) call removed from cmdline;  sleep(0.1) call added inside the cycle 
    while i < repeat_times: 
in order to fully write the output results to log file
