Restructure deeply: now we have a single activity, with a dedicated adapter.

The UnicodeArrayAdapter displays a list of UnicodeDisplayable, which
can be either UnicodeCharacter or UnicodeCharacter.Range, and provides
appropriate views for either one.  Rather than changing activity, we
change the ListAdapter.  To simulate an activity stack, we capture the
back key.
