- split ScalarInstrumentedAttribute into a "scalar" and an "object" version.
The "object" version loads the existing value on set/del, fires events,
and handles trackparent operations; the "scalar" version does not.
- column loaders now use the "scalar" version of InstrumentedAttribute, so that
event handlers etc. don't fire off for regular column attribute operations.
- some adjustments to AttributeHistory to work properly for non-loaded attributes
- deferred column attributes no longer trigger a load operation when the
attribute is assigned to. in those cases, the newly assigned
value will be present in the flushes' UPDATE statement unconditionally.
