rtorrent customizations for crappy DSL line and WDLXTV

from
http://wiki.wdlxtv.com/How_to_use_rTorrent
and
http://grenage.com/rtorrent.html

Most options are set via the web frontend of the WDLXTV (after some basic things were done) except the following which refuses to save, somehow

file: /root/.rtorrent.rc

# Maximum and minimum number of peers to connect to per torrent.
min_peers = 40
max_peers = 100

# Same as above but for seeding completed torrents (-1 = same as downloading)
min_peers_seed = 10
max_peers_seed = 50

# Maximum number of simultanious uploads per torrent.
max_uploads = 3

# Global upload and download rate in KiB. "0" for unlimited.
download_rate = 600
upload_rate = 60

# Encryption options, set to none (default) or any combination of the following:
# allow_incoming, try_outgoing, require, require_RC4, enable_retry, prefer_plaintext
encryption = allow_incoming,require_RC4
