Update "libtorrent" and "rtorrent" package to version \ 
0.12.5/0.8.5:
- Add support for any number of custom download values identified by
  string keys.
  d.set_custom=key,value
  d.get_custom=key (returns "" if not set)
  d.get_custom_throw=key (returns error if not set)
- With this patch, rtorrent will detect and complain about .torrent
  files with broken bencode representation (e.g. where the order of
  dictionary keys is not lexicographic).
- Choose a different poll type using the RTORRENT_POLL env. variable
  (if it's implemented), probably only useful as RTORRENT_POLL=select.
- Add the commands execute_capture and execute_capture_nothrow that
  work like their other counterparts but return the OUTPUT (stdout) of
  the given command.
- Fixes the code that detects which peer was sending bad data. Peers
  are then automatically banned after sending three bad chunks.
- Stops rtorrent from always creating and resizing ALL files, even
  those set to "off". Files will still be created, but with a size of
  zero, until a part of them is getting downloaded. This helps with
  filesystems that don't support sparse files (such as FAT, HFS+, and
  others).
- Fix inefficient piece distribution due to linear chunk request
  strategy by randomizing position every few (on average 32) chunks, see
  ticket #190.
- Enable custom throttles, both per-download or per-IP. See
  http://libtorrent.rakshasa.no/ticket/20 for info and instructions.
- Fix crashes/errors due to rtorrent attempting to pass non-utf-8
  strings to xmlrpc.
- Added support for using posix_fallocate on newly resized files.
- Include locally available chunks in the "chunks seen" statistics for
  completed/distributed copies. Patch by Josef Drexler.
- Added 'd.get_bitfield' command for retrieving the bitfield in hex
  format. Patch by Thomas Rosner.
- Fixed include headers for gcc-4.4.0. Patch by 'kloeri'.
