Allows configuration of the cost of movement along railroads, roads and rivers as well as the movement cost for units with the alpine flag.
These multipliers are configured using the @COSMIC2 keys 'RailroadMultiplier', 'RoadMultiplier', 'RiverMultiplier' and 'AlpineMultiplier' and can be enabled individually.They take 2 values, the first needs to be set to 1 to enable the multiplier, while the second value determines the movement cost. E.g. setting 'RailroadMultiplier' to 1, 6 means a unit can move 6 tiles along a railroad for 1 movement point. Setting the movement value to 0 means the movement cost of the underlying terrain is used, setting it to -1 means movement is unlimited.
In game, all enabled movement multipliers are combined into an aggregate movement multiplier (exactly their least common multiple). This number multiplied by the movement rate from @UNITS must be less than 256 for each unit. You'll get a friendly warning when this limit is exceeded.
If Lua is enabled, registers the 'totpp.movementMultipliers' table.
