- Helper base class: Named
Subclasses: OfficiallyNamed, UnofficiallyNamed
for these, a 'name' column is created in the appropriate text table
also, they get automatic __str__/__repr__/__unicode__
- Faux columns: ProseColumn, TextColumn
these become columns in the appropriate text tables
these text tables (*_text, *_prose) are auto-generated at the end
the main table gets one property (singular name) that gets the English text
and one (plural name) with dict of texts keyed by language
- Every named table gets 'identifier'
- Languages compare & hash equal to their identifiers
- Existing foreign-name tables replaced by the autogenerated ones
- order_by: names replaced by identifiers
- New function: all_tables(), yields all tables
- Markdown move properties removed for now
- Schema test suite
