'AugmentedFillType' for URF-seeders - Test.

The URF-seeders must add +128 to FillType when calling SprayerAreaEvent.
This will instruct SoilMod to use a different spray-sub-function that
ignores crop's first-growth-state.

Example:
SprayerAreaEvent.runLocally(sprayingAreasSend,
Fillable.FILLTYPE_FERTILIZER + 128);
g_server:broadcastEvent(SprayerAreaEvent:new(sprayingAreasSend,
Fillable.FILLTYPE_FERTILIZER + 128));
