(svn r10972) -Codechange: Implement the counterpart(GetTranslatedIndustryTileID) of getindustileid of TTDPatch. This allows to ensure that the ID of a tile (taken out of the map or not) is still a valid one regarding the possible override it may have been flagged to.

It is not the strict same thing, but is what we need regarding the slightly different approach we took for newindustries.
