Update "libtorrent" package to version 0.11.4 and "rtorrent" \ 
package
to version 0.7.4. Changes since versions 0.11.1 and 0.7.1 respectively:
- Added "max_open_http" option that limits the max number of simultaneous
  http connections. By default set to 32.
- Directory structured view of the file list. The '/' key collapses
  directories, while the right arrow or ^F enters the selected directory.
  Changing the priority for a directory changes all contained files.
- Added "create_link" and "delete_link" options which apply \ 
to a download.
  These must be used with the new "on_*" options, so as to allow you to
  create symbolic links when starting, stopping, finishing, etc, a torrent.
- The "tos" option was parsing the hex value with unit == 0, which caused
  it to always zero it.
- Forgot to check if there were any torrents hashing before starting new
  non-fast-resume checks, which would cause multiple torrents to be hashed
  at once.
- File progress is now updated when hash_check is called, and no longer
  cleared on close. This fixes a bug with >100% file progress being reported
  and optimizes file progress updating for completed torrents.
- Disabled IPv6 http requests so the trackers won't think we support it,
  and enabled curl's support for gzip encodings.
- Added 'seeding' view on key 8.
- Added "max_{up,down}loads_{div,global}" options. See the man page for
  more information.
- Added support for dvorak keyboard layout. Patch by matled at gmx.net.
- The STOPPED request was being canceled when a download was closed with
  f.ex ^K, moved it so it only happens when the download is removed.
- Allow properly quoted and escaped arguments to options. F.ex "schedule
  = wd,10,10,load_start=~/Foo\ Bar/*.torrent" and "schedule =
  wd,10,10,load_start="~/Foo Bar/*.torrent"" now works.
- Added unlimited setting for max unchoked in ChokeManager and made it
  the default. Set with 0 as a temporary hack.
- Don't resize empty files used for creating directories.
