Bad order of options "mf" in command jar

[SandrineProusteau]

Seems that in "jar" command, loading order of manifest and jarname is reversed:
line 66 to 81 in run_java.js :

if (data.jarOptions.indexOf("f") > data.jarOptions.indexOf("m")){
        if (data.manifestName){
          execString += " " + data.manifestName;
        }
        if (data.jarName){
          execString += " " + data.jarName;
        }
      }
      else{
        if (data.jarName){
          execString += " " + data.jarName;
        }
        if (data.manifestName){
          execString += " " + data.manifestName;
        }
      }
