#221 colour edges of polyhedra separately from their polyhedra

[Angel Herraez]

It would be nice to add the feature of colouring the edges of polyhedra separately from their polyhedra, thus allowing something like

$ select silicon
$ polyhedra 4
$ color polyhedra blue
$ polyhedra {*} EDGES
$ color EDGES red
