Localization algorithm

1. Make list of all resolvable IDs worrying just about the default ids not
localized ids
2. Make mapping between ids, again not worrying about localization.
3. When creating entries and assets, make the most localized version
possible for each localized node i.e. get the localized field if it exists
or the fallback field or the default field.
