/executable async on|off

 * rename call_external() to call_external_async().
 * add call_external_fork(). This function makes all executable calls
to be forked and synchronous. So that running profanity inside a TTY,
we can set all executables to be TTY programs (fbi, mpv, w3m, emacs
eww, etc.), making possible to open urls or see images inside the TTY.
 * add '/executable async' command.
 * make call_external() use either call_external_async() or
call_external_fork(), according to the '/executable async'
configuration.
