Summary: Allow redefinition in interactions pane

Initial Comment:
From the interactions pane:

> int i = 3
> int i = 4
Error: Redefinition of 'i' 

As the Java language dictates, this is an error.  But
since the language used in the interactions pane isn't
*really* Java anyway, why not allow a looser
interpretation of the above code, and simply replace
the old definition of 'i' with a new one?

This error shows up a lot when some mistake is made in
defining a variable.  For example:

> MyObject o = [long, complex expression here]
[user notices a mistake in the expression and presses 'up']
> MyObject o = [long, complex, modified expression here]
Error: Redefinition of 'MyObject'

It seems obvious in such cases that the user wants to
bind 'o' to the second instance.
