Proposal to extend recncell

[Derek Atkins]

1) remove the get_string callback (it wont be necessary)

2) provide two more setter functions:

	void gnc_recn_cell_set_valid_chars (RecnCell *cell, char *chars,
					    char default);
	void gnc_recn_cell_set_char_order (RecnCell *cell, char *chars,
					   char default);

3) store these two strings in the RecnCell structure

I believe that this is sufficient to get the functionality we need.
In order to get the current RecnCell functionality, given English, we
would use:

	gnc_recn_cell_set_valid_chars (cell, "ncyf", 'n');
	gnc_recn_cell_set_char_order (cell, "nc", 'n');

This would provide the same functionality we currently have..  You can
set and of n, c, y, or f as valid characters, but clicking on the
window will switch between n and c.  If an invalid entry is provided,
it defaults back to 'n'.

This interface is rather crude, but it would provide enough
functionality for what I need.

Comments?
