- META.json is now a UTF-8 file, rather than ASCII
- document the use of filefinders in [PkgVersion], and remove
filtering out of .t, .pod files; do skip non-text files, though
- always load modules in "extra tests" like pod-coverage.t
- PruneCruft also prunes ./fatlib
- avoid being tricked by statements in END section when looking for
variable assignments
- if "dzil install" fails due to exception, it is now propagated
- provide a better error when terminal encoding can't be determined
