Mike Bayer 2ebbdfa405 Emphasize context managers when working with Core ...

Prep the main documentation for the changes coming up in 1.4
by first removing references to engine.execute() outside
of the "connectionless" section, and using context managers
in all cases.  For features that have always been confusing
and are going away, add a note that this feature will
be going away.
