add psql FOR UPDATE OF functionality
added ORM support
Fix sessionmaker.__repr__

A comma separating 'class_' from the other args. It's still there even when kw is empty, which is syntactically correct.
Remove reference to defunct class

We should probably reword this entirely as, IMHO, this should be in the
changelog and not in the doc proper (which should only describe the
current state of affairs).

added LockmodeArgs
Merge branch 'for_update_of' of github.com:mlassnig/sqlalchemy into for_update_of
- work in progress, will squash
- fix up rendering of "of"
- move out tests, dialect specific out of compiler, compiler tests use new API,
legacy API tests in test_selecatble
- add support for adaptation of ForUpdateArg, alias support in compilers
- add support for specifying tables or entities for "of"
- implement Query with_for_update()
- rework docs and tests
- repair the "lockmode" functionality of load_on_ident().  slightly problematic
here is that "lockmode" is also public in Session.refresh().
- changelog, migration
