contacts @1.1_1: Outdated and buggy, no maintainer, should be replaced or additional port added

[herrbischoff (Marcel Bischoff)]

This application has been last updated in 2003. It does deal properly with UTF-8 characters and does not integrate easily into Mutt. There are several alternatives, the most recent being ​https://github.com/keith/contacts-cli, which checks all the boxes, although loses some functionality. Therefore it may be best to add a new port called "contacts-cli" for this, which cannot be installed at the same time as "contacts".

Homebrew exchanged "contacts" for a newer fork (​https://github.com/dhess), which is also unmaintained since 2014 but works with UTF-8 characters. Additionally, there is a "contacts-cli" formula for the aforementioned alternative.
