Ship Reports Transporter "unavailable" when damaged

[Vectorus]

The only other times when transporters can't be used, "beyond range", "insufficient power", "shields up" or "already active" are covered by their own messages. Therefore, I believe the "unavailable" message always refers to inoperability, and the experienced player already knows not to keep trying. There is then no reason not to change it to the more precise "transporter is inoperable".

I assume the "unavailable" message may also be used generically for unhandled failures when a bug is affecting transporter code, but I have never seen it happen.
