(svn r10274) [0.5] -Backport from trunk (r9961, r10023, r10028, r10030, r10038, r10147):
- Fix: Some bits were unset when loading old TTD savegames when they shouldn't be unset (r10147)
- Fix: Sprite resulting from '?' substitution was reloaded into the cache entry for SPR_IMG_QUERY instead of the original sprite cache entry. This resulted in unaccounted missing sprite cache memory, and was exacerbated because the original missing sprite was not cached, so it did it again and again and again. Slowdowns and boom (r10038)
- Fix: One could build on (some) slopes when building on slopes was disabled [FS#823] (r10030)
- Fix: When deleting the first engine of a train with multiple engines, only reopen the train window if the player had the original train window open. This fixes 'random' windows opening for multiple players of the same company (r10028)
- Fix: When selling trains, if there were no wagons between multiheaded engines the rear part could be checked despite having already been deleted (10023)
- Fix: Some files were still in iso8859-15 instead of UTF-8 (r9961)
