Create a migrate.js file to handle data migration

How about combining `move` and `moveWithFunction` into one function with an optional parameter?
 
   move: function(oldModuleID, oldOptionName, newModuleID, newOptionName, transformValue) {
        try {
            var value = RESOptionsMigrateGetRawOptions(oldModuleID)[oldOptionName].value;
            if (transformValue)
                 value = transformValue(value);
           }
           RESUtils.setOption(newModuleID, newOptionName, value);
     }
