update the file modification date is a little time-consuming #73

Thank for giving us a a nice project for zip and unzip. But when I unziped a lot of documents, the efficiency will slow down. I use instrument's time profile to see that updating the file modification date cost 38.8% of method UnzipFileTo:overWrite:. I think most of us don't care about the file's modification date, so this operation should be deleted or have a choice? Thanks.
