[Muine] Three new code cleanup patches

[Tamara <foxxygirltamara gmail com>]

So Muine got some lovin' over the weekend. 

Muine-CVS-20041226-GConfValue
http://bugzilla.gnome.org/show_bug.cgi?id=162298

Cleans up the use of GConf (shortening the code by 100 lines!)


Muine-CVS-20041226-SignalUtils
http://bugzilla.gnome.org/show_bug.cgi?id=162300

Adds a new class, SignalUtils, which contains delegates and wrappers
for g_signal_connect_data.


Muine-CVS-20041226-PrivateVariables
http://bugzilla.gnome.org/show_bug.cgi?id=162301

Removes all use of public variables. Public variables are considered a
BadThingTM. Variables which are used in other classes should be
accessed with a property.

The property for GConfClient can be removed if the GConfValue patch is accepted.


As these are my first patches for Muine, I'm very excited to hear your comments!
