Better plotting of polyhedra

* Reinstate the polyhedron.plot(projection_direction=...) option
* Fall back to plotting the affine hull if necessary
* Implement affine hull
* Refactor plotting
* Add plots for 1d, 0d polyhedra for completeness.

trac #16622: More doc fixes
Move inversion of unit
added macaulay resultant to multivariate polynomial class
Make projection objects display as graphics

They are only used in the graphical display, so let them display as
graphics by default if possible. Also, rename Projection.show->plot
for consistency (show = plot + run viewer).
Fix deprecations and doctests
improved docs and general cleanup
