* Cleaned up torrent::Rate and moved it to the API. Changed various

parts of the API to return torrent::Rate instead of specific functions
for each stat.

* Use 600 second time span for peer rates.

* Added core::DownloadFactory which allows for an async http get and
changing of settings. This will allow the implementation of a
configuration screen when pressing "return", while the client is
downloading or finished downloading a torrent file.
