Rework the way IDF's SCM interface provides downloadable snapshots. Instead of returning a command which gets executed and which should pass through / stream its output data to the client, we're just returning an instance of Pluf_HTTP_Response. This is needed, because some SCMs, most noticable monotone, have no locally executable command to provide a snapshot archive (and probably never will for our kind of setup). We therefor added a little BSD-licensed class "ZipArchive" which allows the creation of pkzip-compatible archives on the fly by letting it eat the file contents directly feed from the (remote) stdio instance. Download performance is ok and lies between 15K/s and 110K/s, but at least we do no longer block the browser while we pre-generate the zip file server-side. Thanks to Patrick Georgi for all his work!

Based on PKZIP appnotes, which are included here.
