fix for wrong sequence name quoting
fix for wrong sequence name quoting 2
reverted test to quoted rname
rname passed asis. freedom in table names and field names. Case sensitivity in field and table names
removed test of allowed char sequence in table and field names, there is no limit anymore
fixed some troubles with postgresql drop(). Better Row.__getitem__(): should not be much slower. Added a ignore_field_case parameter to allow Field('F')!=Field('f') on databases supporting case sesitivity.
different mysql drivers handled in quoting test.
improved handling of foreing keys
fix with quoted names in SQLTABLE. fix for ORDER BY
handle references on non "id" fields
check reference expression against table list first
