(svn r10277) [0.5] -Backport from trunk (10116, r10128, r10130, r10131, r10137, r10138):
- Feature: console command to get the current game date (r10137)
- Fix: When you got a sufficiently small resolution, there is a possibility for a division by zero when a sound is played (r10138)
- Fix: When removing a dock, a ship will always try to reach the old location of the dock even when it cannot anymore because it the old location of the dock is now land instead of water [FS#810] (r10131)
- Fix: SetCurrentGrfLangID returned the wrong language ids for most languages (r10130)
