Update a whole bunch of things

Yeah... not a great commit message. t.b.h, I could maybe've split the
commit into more parts; but that would be quite a lot off effort and
would have a pretty decent chance of at least one of the commits leaving
the repository in a non-working state.

For the future, will want to try and commit more often so there aren't
these mega-commits where it's just "a whole bunch of stuff changed"
