Merge pull request #33 from bhull2010/master

Restore volume-step preference instead of hardcoding it
[general] replace deprecations, use GDK X11 API, bump GTK+ to 2.24

for:
gdk_x11_window_lookup_for_display()
gdk_x11_window_foreign_new_for_display()
[keyboard] don't use deprecated gdk_spawn API.

And use:
gdk_display_get_app_launch_context() on GTK3
gdk_app_launch_context_new() on GTK2
[mouse] remove deprecated gdk_drawable_get_size & gdk_drawable_get_screen

Since we now require GTK 2.24, we can directly use
gdk_window_get_width(), gdk_window_get_height(), and gdk_window_get_screen()
