Version the fatpacked recs with either an explicit or git-based version

This preserves the usefulness of recs -v if recs has been installed from
https://recs.pl, which points to the copy in master on Github.

The support for providing an explicit version will be used when updating
recs as part of a CPAN release.
Install all fatlib modules without recommends or suggests prereqs

This protects against a default recommends or suggests setting affecting
`devel/update-fatlib --upgrade-local` too.
Move to vanilla Dist::Zilla

Milla's philosophy of keeping the repo installable/hackable is very
nice, but using it's plugin bundle makes it hard to further customize
the build/release process precisely (hence the need for the @Filter
hacks).  Being unable to insert a step between release and auto git
commit was the last straw.

This commit unbundles Milla into a vanilla Zilla config.  To do so, I
referred to Dist::Zilla::PluginBundle::Milla.  Where sections were
filtered out or modified by our previous dist.ini, I removed/merged
them.  Ordering changed a little but is largely based on the "known
good" of Milla's.
