Get tests working to test `prettify_hipchat` sub

* test.sh: Create a temporary file `prettify_hipchat.pl` that contains
  only the `prettify_hipchat` subroutine. Then run `test.pl`. Finally
  remove the file we created to contain the subroutine.
* Require `prettify_hipchat.pl` from test.pl. This file contains only
  the `prettify_hipchat` subroutine, allowing us to require it without
  concern.
