-Important bugfix to DownloadManager. Didn't obey the reask time rules properly. Could lose some sources due to this.

-Went back to the smaller buffers of upload slots, since some reports say it worked better with them.

-You can now get an ed2k link from someone that includes a source and click on that link to add the source even if you have started downloading the file (and already got chunks shared).

-Tagged some source code lines for DownloadManager that was missed earlier.
