Attached is a new port, net/texnut, a command-line client for the
pnut.io social networking service. It is mostly identical to net/texapp.
Additionally, net/texapp should be removed. The service texapp targeted
has shut down, rendering this port now useless. However, texnut should
not be viewed as an upgrade to texapp, as there's no reason to assume
users of one service migrated to the other.
