Drop List::MoreUtils as a dependency

List::MoreUtils was adopted upstream, which is wonderful, but the
development versions of List::MoreUtils are going places I don't really
fully understand. I'm sure I'll revisit later, but right now I'm worried about
relying so heavily.

I've also tried really hard to keep Sub::Exporter out of the dependency chain,
but there it is again! DAMMIT

It's a shame to lose the XS implementations of certain bits, particularly
uniq(), but I'll probably add the little XS bits we need when I find some
round 'tuits.
