Catalina-compatible release

Version 0.0.2 is compatible with macOS Catalina 10.15.5.

• It fixes the incorrect entitlement structure, which earlier macOS versions erroneously accepted as valid.
• It is built with Swift 5, so it will not run on older macOS versions, which do not include the Swift 5 runtime.

NOTE: the entitlement issue, unfortunately, means that macOS will treat this as a new application, which will have no access to the previously added keychain items.

First experimental release

This version is built with Swift 4 and contains the Swift 4 runtime statically linked.

It should run on all macOS Mojave versions.
