(svn r20305) -Change: reduce OpenTTD's install size by roughly 460 KiB by only providing the "extra" base graphics in one palette and doing the conversion upon loading; the conversion has existed for a while, but now the NewGRF can tell its palette using Action 14 thus it can enable the conversion for only that NewGRF.
