changelog entry for meta improvements
bump version to 3.14
add a placeholder .mailmap
tighten up entries
we have no prereqs; might as well enforce that
remove unneeded plugin
documentation improvements
insert dist version into pod, rather than module version

I wanted to do this with Pod::Weaver, but I couldn't find a nice way of
snipping out the original section and replacing it in the same order.
Would I really have to crack into [@Default], copy all its bits out and then
replace [Version] with [Template / VERSION]?
ensure other version-mangling plugins aren't used
since we set our version manually, test that it changed from the last release
Acme-Pi-3.14
