Title: async.done not being called if there are no input files.

I've added a call to async.done if the length of files is 0. This can happen in the case where there is a filter on the files based on modification date, e.g.

files:[{ expand:true,
cwd:"js/",
dest:"js.min/",
src:["**/*.js"],
filter: function() {
/* return true here if source file is newer than the output file */
}
}]
