Subject: Try to listen on a FIFO for the updated message

All kinds of things wrong with this, I'm just fiddling to try to see if
I can get something to work. This blocks Irssi, which is bad.

* Rename `tempfile` to `vimput_file` so as not to collide with the
  `tempfile()` function that creates a temporary file.
* Add a new sub that ostensibly is supposed to read from a file handle
  and print the message received.

Read
https://github.com/shabble/irssi-docs/wiki/Guide#Dealing-with-Blocking-IO
and
https://github.com/shabble/irssi-scripts/blob/master/feature-tests/pipes.pl
I feel like I have a better idea of how to deal with this using `fork`.
