net-p2p/deluge-cli: update to 2.1.1

fixes:

• pidfile for deluge-web
• long options in command_args to make it easier to read
• remove deprecated -f (fork) option, it's now default and there is no way to explicitly negate the new option --do-not-daemonize
• use *_confdir variable in command_args instead of $required_dirs which just happened to have the same value (more explicit this way)
• remove setproctitle dependency to allow stop/restart of service (process cannot be found otherwise)
• replace slimit with rjsmin for javascript minification for web ui
• make PY_PILLOW dependency optional for cli and required for ui (default include)
