(svn r20520) [1.0] -Backport from trunk:

- Fix: Draw error messages in white by default, they may not have a colour set when coming from a NewGRF (r20514)
- Fix: Entering half the 'generation seeds' in the console's 'newgame' command failed to set the correct seed [FS#4036] (r20512)
- Fix: Desync when converting rail all as trains with a part on the converted rails need updating and not only the engines (r20500)
- Fix: Ignore the non-stop state when comparing one order type to another order type, otherwise non-stop nearest depot orders fail [FS#4030] (r20498)
- Fix: Non-dedicated servers failing to load a game caused the introgame to be the server's game causing desyncs when people tried to join [FS#3960] (r20497)
