(svn r23817) -Fix [FS#4962]: desync due to different NewGRF version. So reduce the chance that it happens significantly with betas/RCs/nightlies by doing the same as is done for stable releases: check the NewGRF version of server vs client.
Previously this check was not done for nightlies/betas/RCs due to missing versioning information in the source tarballs, but they have that for a while now. So just force the NewGRF version check for all versions, and remove the broken --revision configure option
