Check for engine pool being enabled
Enabling the engine pool is a good idea and saves trouble with people loading multiple sets. What about just disabling this newgrf, if it's off?
However the answer, though, we should at least take some kind of action.
Engine pool is variable 85, flag 78 ( http://wiki.ttdpatch.net/tiki-index.php?page=TTDPatchFlags )

Please test the attached diff whether it does what we want (it only issues a non-fatal error, if the engine pool is off).
Also, I wondered about: as it is now, the cargo translation table is skipped, if we have a current OpenTTD version. That might be the cause that it didn't work with it in recent versions of this set. So, my guess is, this diff also fixes another problem (issue #142).
