Added a new event suite :class:.QueryEvents. The
:meth:.QueryEvents.before_compile event allows the creation
of functions which may place additional modifications to
:class:.Query objects before the construction of the SELECT
statement. It is hoped that this event be made much more
useful via the advent of a new inspection system that will
allow for detailed modifications to be made against
:class:.Query objects in an automated fashion.
