Add support for upgrading older perls in-place.
This fixes GH #150
I just realized that this new command will not preserve options you used to build the current perl. Still might make for a good base of implementation, though.
Is there a straightforward way to get those options from the built perl executable?
@doherty perl -V, or Config.pm, I think.
