last change Heavy configuration management refactor
- Configuration groups now take both an on_change event handler and a
default keybinding handler, making most keybinding tasks quite simple
- GUI configuration all merged into a unified model, drastically reducing
the amount of GUI config code.

Bonuses
- OSX now has a hotkey preference pane
- GTK keybinding editor is much more usable

nkeynes@144
     6
 * passed to the appropriate dreamcast controllers (if any).

/* Some explanation:
nkeynes@614
    39
 *   The system has at least one "root" device representing the main display 
nkeynes@614
    40
 * (which may be the null display). This device is part of the display_driver
nkeynes@614
    41
 * and generates events with no input_driver. The root device has no id
nkeynes@614
    42
 * as such (for the purposes of event names)
nkeynes@614
    43
 *
nkeynes@614
    44
 *   The system may also have one or more auxilliary devices which each have
nkeynes@614
    45
 * an input_driver and an id (eg "JS0"). So the keysym "Return" is (de)coded by
nkeynes@614
    46
 * the root device, and the keysym "JS0: Button0" is (de)coded by the JS0 input
nkeynes@614
    47
 * device as "Button0".
nkeynes@614
    48
 *
nkeynes@614
    49
 *   For the moment, mice are handled specially, as they behave a little
nkeynes@614
    50
 * differently from other devices (although this will probably change in the 
nkeynes@614
    51
 * future.
