Add ability to show full digit maps

Full digit maps will show every digit from 0 to 35, regardless of the
radix.  This allows you to see extra fractions for small radices and to
get a digit map for radices above 36.

This isn't enabled by default because the extra "digits" added for small
radices aren't actually digits - so it may be unintuitive.  There are
also some situations where only a radix's actual digits matter, such as
multiplication tables.
