• Installing from local archive files (i.e. zef install ./foo.tar.gz) now works. Previously such archive files could be installed only if they were part of a remote url that needed to be fetched.
• Zef::Repository::LocalCache can have it's work directory set using a string in addition to an IO::Path. This allows setting e.g. "options" : { "cache": "/tmp/some-dir" } in resources/config.json.
