switch_terminal verb config parameter (#693)

Broot runs in an "alternate terminal".
By default,  broot switches back to the normal terminal during the execution of a program it launches, then back to its alternate terminal on end of the external process.
In some cases, this adds an unnecessary flicker.
The `switch_terminal` verb parameter, whose default value is `true`, lets you disable this behaviour.
