hcid man page update

Hi

Attached is a new hcid man page update. Except for default device
paramater inheritance and the device specific "autoinit" paramater,
it should be accurate but somewhat incomplete for hcid-2.4-fn8 at:

   http://noring.nocrew.org/bluetooth/

Next I plan to implement persistent DBus device configuration
management. This will make hcid and the Gnome Bluetooth Configuration
tool ready, feature wise, for an initial release, I think.

I suspect Marcel has more comments on the extended interfaces etc. so
these will probably be adjusted in the future.
