[Axiom-developer] mathml derivative patch

[Arthur Ralfs]

Tim, Waldek,

This patch fixes the problem with derivatives Tim found, e.g.
F:=operator F
x:=operator x
y:=operator y
a:=F(x z,y z,z**2)+x y(z+1)
D(a,z)

However I've had to abandon differential notation for now, although I'd like
to find some way to use it when appropriate, or perhaps give the user the option
of trying it.
