(svn r22152) [1.1] -Backport from trunk:

- Fix: Windows video driver crashed when it could not go to full screen at the resolution of the configuration file when starting OpenTTD [FS#4521] (r22149)
- Fix: Do not run savegame conversion during SlNullPointers; the pointer might not be converted or be NULL at that point (r22146)
- Fix: Some valid keycodes were ignored along with the invalid ones (r22142)
- Fix: When commands need to invalidate windows, process these events asynchronously before the next redraw. Calling window code directly from command scope uses wrong _current_company and might issue nested DoCommands() which interfer with the running command [FS#4523] (r22141, r22140, r22135, r22134)
- Fix: [NewGRF] Skipping only the invalid part of an action14 failed, the rest of the action was skipped instead (r22138)
