added special 'property' field to columns

When defining a column, you can specify a "property" field
that will allow a more programmer-friendly name to be used
when selecting fields.

e.g.

var user = sql.define({
  name: 'user',
  columns: [{ state: 'state_or_province', property: 'state' }]
});

user.select(user.state);
