clearer than how it was done before.

Add a View/Toolbar setting

A good setting to demonstrate one-way binding is the View/Toolbar
setting. When the menu item is switched on or off, we want to update the
setting, but not the other way around. This is so that when you have
multiple windows, turning the toolbar off in one doesn't turn the
toolbar off in the others, but when you open a new window, the toolbar
is shown or hidden depending on the last choice you made.

Create configuration directory

On startup, the player application now creates a configuration
directory, ~/.chimara. The preferences file is ~/.chimara/config, unless
there is a file chimara-config in the current directory, in which case
it will be overridden.

Add 'state' settings; add last opened path setting

The settings file now discriminates between 'preferences' settings,
which the user sets from the preferences dialog, and 'state' settings,
which are things remembered by the program.

As an example state setting, the program now remembers the last path a
game was opened from, and automatically starts the file chooser in that
path when opening a game.

Philip Chimento [Sat, 26 Feb 2011 16:15:35 +0000 (17:15 +0100)]
Introduce preferences file

We now use a GSettings object with a custom backend that writes to a
configuration file, ~/.chimara. Right now there is only one example
setting, "flep". It's easy to bind the setting to a property of another
GObject, like the "active" property of a checkbox.

Still need to check how other GLib applications install the settings
file properly in their Makefile.am, and how to work with a default
configuration file such as /etc/chimara if the one in the home directory
is not present.
