(svn r20869) [1.0] -Backport from trunk:

- Fix: [NewGRF] Assert when an industry previously build on water was flooded because its NewGRF changed/is missing [FS#4112] (r20754)
- Fix: Do not use new game settings when creating many random towns/industries in the scenario editor [FS#4094] (r20712, r20711)
- Fix: Graphic glitch when switching to a different-sized font while the chat message box was visible (r20705)
- Fix: Vehicle lists of non-trains could not resize horizontally causing truncation of texts [FS#4123, FS#3955] (r20174)
