First draft of a table for params.

params are camera settings stored in the cameras on-board flash memory. This means that unlike PropertyCase they are remembered even if the camera is turned off.

Camera params can be mapped using CHDK/SCRIPTS/EXAM/paramdmp.lua script


params are different for Digic II and Digic III, and most probably even for different platforms.


# Description
19 Display Brightness - seems to reflect the setting for the display brightness
20 Mute sounds - mute on or off
87-89 Interval - interval settings, number of shots and time between shots (details later)

NOTE: these values imo arent really right yet for S3IS, but i have not created a proper compare params function (yet).
