[PATCH] Store the main window maximized state in the configuration

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

In save_window_geometry() use gdk_window_get_state() to retrieve
the window maximized state and store it in the user configuration.
Then in restore_window_geometry() restore the maximized state with
gtk_window_maximize(), if needed.

A side effect is that the windows resize now only occurs if
the window wasn't maximized, otherwise clicking the "restore"
(or "un-maximize") button will simply remove the maximized state,
but the window will remain with fullscreen dimensions.
