bug: not helpful when missing $EDITOR

[prenex]

STEPS:

• Tried to "kanban 1" (editing of id 1) on a machine where $EDITOR was not set.

EXPECTED:

• Some error message that is meaningful for missing variable

HAPPENS:

• Some cryptic error message. I found out that this was missing by guesswork.

I understand that you pretty much best have that set anyways, but it would be helpful to add a better message. Show, init, etc. usually works (I have this "tput: unknown terminfo capability 'normal'" other error though, but everything seems to work with it).

SOLUTION:

• Add EDITOR env var on your machines
• But would be nice if software tells us.

tried export EDITOR=vim should work? I still get the same error
