[Cairo] Remove part of the dependency of FL/Fl.H on config.h.

To use Fl_Cairo_Window one did not only need to configure with --enable-cairo,
but also needed to #include <config.h> before #include <FL/Fl.H>.

This commit removes the smaller part of the dependency of the public header
file FL/Fl.H on config.h. This needs a better solution in FLTK 1.4.0.

The user still needs to define FLTK_HAVE_CAIRO _before_ #include <FL/Fl.H>.

Note: This is not compatible with fluid, since fluid _always_ includes
FL/Fl.H as the first statement in generated header files.

Note: also fixed a typo in src/drivers/X11/Fl_X11_Screen_Driver.cxx

       This is not the default, because it may not be necessary
       to add cairo support to all fltk supported windows.
       When you wish to associate a cairo context in this mode,
       you need to call explicitly in your draw() overridden method,
-      FL::cairo_make_current(Fl_Window*). This will create a cairo context
+      Fl::cairo_make_current(Fl_Window*). This will create a cairo context
       but only for this Window. 
       Still in custom cairo application it is possible to handle 
       completely this process automatically by setting \p alink to true.
