tuning Gtk+ for embedded (was: GtkSheet)

Here's what I started working on.

 * made a --enable-customize switch in configure file (turned off by
default so that build won't be affected)

 * include dependencies.h header in acconfig.h/config.h if the
enable-customize is defined, else nothing happens.

 * in the dependencies.h are two things:
   - the user defines the widget he wants to use ( this is off the
configure system and may be handled by a small UI app )
   - a set of tests completes ommited widget (like including gtkwindow
would automaticaly include gtkobject)
   - another set of test completes with the widgets to remove.

 * in each and every file add the define tests of the widget so that
   - if the widget isn't explicitly defined as to be removed, then keep
it (this is to ensure that usual build are fine)

I started working on this and may send a patch for the 3 first points
this week end. (dependencie handling will require review by other than
myself since at the moment, I simply care about mother/daughter class
dependence).

Then I'll start working on integrating the define in the code.
I made sure it doesn't impact on the "usual" build but review will be
welcomed.
