using builder to convert to AMD format would loose //>>excludeStart/End blocks

[liucougar]

after using the builder to convert all our code to AMD format, any blocks like the following are removed from the output:

        //>>excludeStart("debugCommentPlugin", true);
        if('_tpUnique' in dojo.config){
                return {datetime:String(24*60*60*1000+dojo.config._tpUnique++*60000)};
        }
        //>>excludeEnd("debugCommentPlugin");

this block should be removed in built release, but it would be good if it's maintained when only doing a AMD conversion build

Set the build switch applyDojoPragmas to falsy (e.g., applyDojoPragmas=0) and all dojo pragmas will be passed without modification.
