Skill should be able to call an command line programm - in best case keep stdio/stdout open

[Kulbartsch]

Feature Request:

Actual Behaviour

Currently it's possible to call a web API (see Turorial Level 11):

{
  "url":"http://api.loklak.org/api/search.json?q=$1$",
  "path":"$.statuses"
}

Requested Behaviour

It would be cool to alternatively call a local command line program, maybe like this:

{
  "exec":"fortune -m *$1$",
  ...
}

Additionally it would be very useful to use a a command line program interactively, sending requests to stdin and accepting answers via stdout without terminating the program during the use of a skill.
