(svn r19120) -Fix: [NewGRF] Industry property 0x17 was interpreted incorrectly and in some cases circumvented the density difficulty setting.
-Change: Do not scale the number of industry creations during map creation with the number of available industry types.
-Feature: [NewGRF] Implement special industry flag 0x10000.

(svn r18726) -Fix [FS#3463]: with non-uniform industries the 'supplies' text when building a station could be incorrect (missing a cargo)
-Change [NoAI]: AITile::GetCargoProduction now returns the number of producers and not the number of tiles of producers.
-Fix [NoAI]: AITileList_IndustryProducing would omit some tiles for at which a station would get cargo.

(svn r18283) -Feature: [NewGRF] Add new price bases for removing industries, building/removing unmovables (new objects), building/removing rail-waypoints/buoys, interacting with town-authority, building foundations, funding primary industries (when not prospecting) and towns.
If a GRF does not set price multipliers for these new prices, but for the previously used ones, the old modifiers will be propagated to the new bases.

(svn r17113) -Change [FS#265][FS#2094][FS#2589]: apply the subsidy when subsidy's destination is in station's catchment area and cargo packets originate from subsidy's source
-Change [FS#1134]: subsidies aren't bound to stations after awarding anymore, they still apply to town or industry, no matter what station is used for loading and unloading. Awarded subsidies from older savegames are lost
-Change [NoAI]: due to these changes, AISubsidy::GetSource and AISubsidy::GetDestination now return STATION_INVALID for awarded subsidies
