menu mnemonics

[James Henstridge <james daa com au>]

I have been fixing up some of the code in gnome-app-helper.[ch] a bit. 
It now handles mnemonics correctly, so keyboard navigation of menus 
works correctly now.

As part of the conversion over to the mnemonics APIs, the uline_accels 
argument to a number of the public API functions no longer gets used. 
We should probably remove the argument from those functions all 
together, except that we are in API freeze.

I also added back support for loading the saved accelerators (previously 
they were getting saved on application exit, but not getting loaded 
again on application startup).  I also converted the code to use the new 
accel_path/accel_map APIs instead of calling 
gtk_item_factory_add_foreign to set up the accels.

I noticed that the Bonobo UI handler isn't doing mnemonics correctly. 
It calls gtk_label_parse_uline(), which sets the underline but doesn't 
set a mnemonic.  This means that underlines appear in the menus, but 
they can't be used for keyboard navigation :(  The call to 
gtk_label_parse_uline() should probably be replaced with a call to 
gtk_label_set_use_underline().

James.
