Settings and preferences

[perriman <chuchiperriman gmail com>]

Hi,

	You can take a look at the upstream-integration branch of

https://github.com/chuchiperriman/kupfer/tree

	Now exists SettingsController in settings.py and I have removed
GconfStore.py. The preferences dialog still not work but you can take a
look at the SettingsController object. I have removed the get_config
function and main.py uses the SC now.

	I have added some configuration to google.py plugin to show how the
plugins can use the gconf_client to store their configurations.

	Please, take a look at the new structure and give me your opinion about
it. 

	The next steps are:

1.- When the user change something in the preferences dialog, we need to
change it in the settings controller.
2.- Someone (in main.py or browser.py, I need to see) will connect to
the SettingsController signals and will change the kupfer objects on the
fly when the configuration changes.
3.- We need to decide what preferences we will add to the preferences
dialog. I don't know if directories/direct, directories/catalog etc,
need to be shown in the preferences dialog or if they are internal.
.

.
n.- Show the plugin list

I go slow but secure :)
