Add history/trace functionality to the GHCi debugger

The debugger can now log each step of the evaluation without actually
stopping, keeping a history of the recent steps (currently 50).  When
a (real) breakpoint is hit, you can examine previous steps in the
history (and their free variables) using the :history, :back and
:forward commands.
