"Shuffle" remote-control, "loop playlist" on/off remote-control switch

Dear alsaplayer-maintainers,

we are planning to use alsaplayer as our playout software here at community-radio "Freies Radio Innsbruck".
To better fit our needs I made some changes:
* added a commanline option "--shuffle, -S" that works as a remote-control to shuffle the current playlist.
* changed the behaviour of "--looplist, -P" to a remote-control option that takes an "on" or "off" argument.
* cleaned an inconsistency for the "--loopsong" option. In the help-output its short version was "-L" whereas in the code it was "-S".

What do you think?
Are you interested in incorporating (some of) those changes?

Greetings
Hermann
