Build script now builds jt65. The tools jt65 and jt65sim usilize the options module for all comamnd line parsing. The tool jt65sim now has conventinal command line options and switchs. Default values have been added where appropriate and options documentation updated. An option to disable PRNG seeding has been added. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6276 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
