fix attempt for issue #28 with --edit-script and --minimization --incoming-pop <file>

[pdreiter]

This turnin request contains a fix to a genprog issue where edits weren't being used with minimized when !minimize_patch is true. Tested solution on minimal scenario identified in issue #28, maximal set provided by Joe Renzullo, and covered all combination of command line cases for --minimization, --edit-script, --incoming-pop <file> .

It looks good in my testing, but please note that I didn't do a full regression test... also note that my update mirrors a similar construct in minimization.ml @ 201-205
