2008-10-05  Thomas Thurman  <tthurman@gnome.org>

        Second half of the switch to using x-macros for keybindings so that
        we don't have lots of places with the same information which must
        stay in the same order.  This time it's screen bindings.

        * src/core/screen-bindings.h: New file, containing screen bindings.
        * src/core/schema-bindings.c: added ability to output screen bindings.
        * src/core/window-bindings.h: tiny tweak to comment
        * src/core/keybindings.c: generate function prototypes using s-b.h;
          several handlers modified to use ints rather than ints cast into
          pointers, or renamed.
        * src/include/prefs.h: generate names of bindings using s-b.h;
          generate screen_handlers using s-b.h;
          arguments to bindings are ints and not ints cast to pointers;
          several handler functions renamed to consistent names.
        * src/core/prefs.c (meta_prefs_set_num_workspaces, init_bindings):
          generate screen_handlers using s-b.h;
          generate screen_string_bindings using s-b.h (and add check for
          null bindings in init_bindings to enable this simply).
