(svn r22837) [1.1] -Backport from trunk:

- Fix: [NewGRF] Always draw NewGRF supplied texts with a default colour (r22725)
- Fix: [NewGRF] Do not restrict AdvVarAct2 to 255 operations (r22723)
- Fix: If there is no point in opening the rail/air toolbar, do not open it for people who use hotkeys either rather than only for those using GUI elements (r22716, r22715, r22714)
- Fix: [NoAI] Allow AIAirport::GetNoiseLevelIncrease() also for expired airports [FS#4704] (r22710)
