New port: deskutils/zanshin

Zanshin is a powerful yet simple application to manage your day to day actions.
It helps you organize and reduce the cognitive pressure of what you have to do
in your job and personal life.
You'll never forget anything anymore, getting your mind like water.

This is based on a version of adridg done way back when kde@ still had an svn repo,
but was unfortunately forgotten about, when the repo moved :)
