Fetch dictionaries from database tables.
The tablename has to be set in [FetchSpecification entityName].
Qualifier, sortOrdering, distinct will be evaluated.
It handles now tables with more than one primary key.
Its possible to set the primary key in the fetchspecification hints
(EOPrimaryKeyAttributeNamesHint -> array with strings as columnnames
for the PKeys; EOPrimaryKeyAttributesHint -> array with EOAttributes for
the PKeys).
If no primary key is set, and now primary key could find in the table
schema, all keys will be taken as primary keys.
If only one primary key exsist, in insert object a new key will be generatet,
else all keys has to be set.
If fetch hint EOFetchResultTimeZone is set (NSTimeZone), this timezone will
be set in date objectes.
