Resizing the name field

Lets you set the length of the different pieces of the "name" field.

In /archives/[ARCHIVE]/cfg/cfg.d/field_property_defaults.pl there are some defaults for the width of various fields - including:

# Default size of the "name" input field parts.
$c->{field_defaults}->{input_name_cols} = {
    honourific=>8,
    given=>20,
    family=>20,
    lineage=>8
};
