	Improved handling of distribution specific menus.

	Rather than providing code for RH and Debian menus, we now
	have some generic "distribution menu" code - all customizing
	is done in a `DistributionInfo' array in distribution.c.

	This makes it very easy for distribution vendors to add a
	custom menu for their distribution (like the already existent
	AnotherLevel and Debian menus) with a about-10-line-change
	in a single source file.

	* distribution.h: New file.
	(DistributionType): Contains all possible Linux distributions.
	(DistributionInfo): New struct type containing info about
	distribution specific menus.

	* distribution.c: New file.
	(get_distribution): New global function; returns the current
	Linux distribution as a `DistributionType'.
	(get_distribution_info): New global global function; takes a
	`DistributionType' argument and returns a `DistributionInfo *',
	this struct contains information about distribution specific
	menus.

	* menu.h (MAIN_MENU_REDHAT): Renamed to `MAIN_MENU_DISTRIBUTION'.
	(MAIN_MENU_REDHAT_SUB): Renamed to `MAIN_MENU_DISTRIBUTION_SUB'.
	(MAIN_MENU_DEBIAN, MAIN_MENU_DEBIAN_SUB): Removed (replaced with
	`MAIN_MENU_OBSOLETE_DEBIAN' and `MAIN_MENU_OBSOLETE_DEBIAN_SUB'
	for compatibility with old config files).
	(DEBIAN_MENUDIR): Removed.

	* session.c (init_user_applets): Use the new distribution menu
	rather than the old RH and Debian menus.

	* panel.c (drop_menu): Don't check for "/etc/X11/wmconfig" etc.,
	but use the new get_distribution () function to get the
	current distribution.

	* menu.c (init_menus): Use the new get_distribution () function
	and run the `distribution_info->menu_init_func' hook if it
	exists.
	(setup_menuitem_try_pixmap): Allow the "try_file" to be NULL.
	(create_distribution_menu): New function. This replaces the
	old create_debian_menu () function but is now distribution
	independent.
	(create_debian_menu): Removed.
	(create_root_menu): Use the new distribution menus.
