The linux buildbots have started to fail compilation due to not
finding the gtk headers. The quotes have been changed to angle brackets
to indicate to the compiler that these are system includes.
specific code. As a result of this, HAVE_GTK3 no longer needs to be
exposed.
The use of HAVE_GTK, and HAVE_ GTK3 have been changed to mirror the
method used by HAVE_QT and HAVE_QT5.

This update replaces depreciated Gtk1.x symbols with Gtk2.x symbols in
preparation for adding Gtk3 support. These edits aim to be fully
compatible with Gtk2.x, allowing backward compatibility.
The following symbols have been replaced in this commit:
Gtk symbols that have been moved to the Gdk library:
- GtkType -> Gtype
- GTK_CHECK_CAST -> G_TYPE_CHECK_INSTANCE_CAST
- GTK_CHECK_TYPE -> G_TYPE_CHECK_INSTANCE_TYPE
- gtk_signal_connect -> g_signal_connect
- GTK_SIGNAL_FUNC -> G_CALLBACK
- gtk_type_class -> g_type_class_peek
- gtk_type_new-> g_object_new
- GtkTypeInfo -> GtypeInfo (Not required for
g_type_register_static_simple)
- gtk_type_unique -> g_type_register_static_simple
- gdk_draw_image_rgb -> replaced by gdk_cairo_source_pixbuf
NB: This requires porting to use cairo contexts and GdkPixbufs.
The following gtk symbols are changed for their modern equivalent:
- GTK_WIDGET_REALIZED -> gtk_widget_get_realized
- GTK_OBJECT_FLAGS -> gtk_widget_set_realized
Symbols without replacement:
- gtk_range_set_update_policy -> No replacement; as default policy is
set to continuous we can delete this line.
