Initial commit of new interface
Changes touching the build: - Bumped version to 0.5.0. - Removed dependency on Xfce libs (it only depends on GTK+-2.0.) - Updated Makefile with new source files. - Build ChangeLog through a script (remove it from source tree.) More generally speaking, the interface is build on top of a GtkBuilder UI definition, with a personal GtkTreeView and a Settings GObject to update the information shown on the interface on changes. All the code is being written with GObjects which will make it a lot easier to separate GUI code and system code.
