plot3d transformations should take symbolic vectors

[jasongrout]

This works:

var('r,theta,z,rho,phi')
cylindrical=[r*cos(theta), r*sin(theta), z]
plot3d(3,(theta,0,pi/2),(z,0,pi/2),transformation=cylindrical)

but this doesn't (but should work)

cylindrical(r,theta,z)=[r*cos(theta), r*sin(theta), z]
plot3d(3,(theta,0,pi/2),(z,0,pi/2),transformation=cylindrical)

The problem is we pay too much attention to the type passed into the transformation argument. We should also allow symbolic vectors, as well as lists and tuples.

Now the transformation also can be done with a symbolic vector
