commit (head): ease customisation of menu layout

One of the issues that the Nokia guys run into is the inflexibility of
our menu layout system; it just gets too messy if you want provide very
different menu layout. I have been thinking about how to make it easier
to customise without completely decentralising it (which would mean
increased maintanance) and I have come up with a simple solution, using
technique based Hub's xap_Features.h

First of all I added add ap_Features.h along the lines of xap_Features.h
(since menus are defined in ap_ space).

If a particular platform wants to provide a menu layout that is
radically different from the standard abi layout, it would create the
layout (using the same technique as ap_Menu_Layouts_MainMenu.h) in
ap_*Menu_Layouts_MainMenu.h (where * is what ever identifier the
platform uses, say ap_HildonMenu_Layouts_MainMenu.h)

As a second step, in its ap_*Features.h it would then include
        #define APF_MENU_LAYOUT_MAIN_MENU "ap_*Menu_Layout_MainMenu.h"
(It also needs to add the appropriate include statements into
ap_Features.h).

I modified the ap_Menu_Layouts_MainMenu.h so that the exsiting
contents are included conditionally:

#include "ap_Features.h"
#ifndef APF_MENU_LAYOUT_MAIN_MENU
        // the existing AW layout comes here ...
#else
        #include APF_MENU_LAYOUT_MAIN_MENU
#endif

I would appreciate if this could be backported before we create a branch
for the N770 merger.
