Add /etc/default/picam-streamer file to allow easy customization

[geefer]

Would it be possible to modify picam-streamer init files and server.coffee/js to make use of an /etc/default/picam-streamer file as you have done for the main picam project? At present the startup for the picam program in picam-streamer is hard coded into the server.js file.

@Geefer It's possible, but requires fair amount of modifications to /etc/init.d/picam-streamer and server.js (or its counterpart server.coffee). If you can just modify command line options in server.js, that's fine.
