ignore swap files, damn it
Implement regex matching on keys:

You can now match key values against regular expressions:

    my $rules = {
        DeployUser => {
            Software => [
                [ 1, { author => qr/^(Sawyer|Mickey)$/ } ]
            ]
        },
    };

This will allow the DeployUser entity to deploy the Software,
if the 'author' is either Sawyer or Mickey.
