Add a -z interpreter flag to execute a zip file

New icons get added so rarely that each time it happens,
Windows has
changed enough to make the instructions invalid... I do
remember
creating icon associations for .py, .pyc, .pyo and .pyw, and
separate
"open" associations for these. IIRC the two
associations are quite
independent. Probably everything has changed though since we
now use
MSI.

You can believe that, but it's not the whole story. You can
*prepend*
arbitrary data and the zip tools can still read the
archive.
