- the "owner" keyword on Table is now deprecated, and is
exactly synonymous with the "schema" keyword. Tables
can now be reflected with alternate "owner" attributes,
explicitly stated on the Table object or not using
"schema".
- all of the "magic" searching for synonyms, DBLINKs etc.
during table reflection
are disabled by default unless you specify
"oracle_resolve_synonyms=True" on the Table object.
Resolving synonyms necessarily leads to some messy
guessing which we'd rather leave off by default.
When the flag is set, tables and related tables
will be resolved against synonyms in all cases, meaning
if a synonym exists for a particular table, reflection
will use it when reflecting related tables. This is
stickier behavior than before which is why it's
off by default.

inline underneath a class declaration. This extension differs
from ActiveMapper and Elixir in that it does not redefine

behavior and table definition.

- state.commit() and state.commit_all() now reconcile the current dict against expired_attributes

needlessly marked as expired after a two-phase inheritance load.
- fixed bug which was introduced in 0.4.3, whereby loading an
already-persistent instance mapped with joined table inheritance
would trigger a useless "secondary" load from its joined
table, when using the default "select" polymorphic_fetch.
This was due to attributes being marked as expired
during its first load and not getting unmarked from the
previous "secondary" load. Attributes are now unexpired
based on presence in __dict__ after any load or commit
operation succeeds.
