Some attachments can have a larger radius than others

[NermNermNerm]

Some tools, particularly watering and scythe, get used a lot in farms that are built around using the tractor. It's really nice to have those tools have a bigger impact area than tools like the hoe, where you'd rather have more precision.

This adds a new setting "ExtendedDistance" to the Scythe, Waterer, Seeder and Fertilizer tools. It's just a boolean setting which allows for one more than the default radius. It's a simple boolean setting to make it simpler for the user. Any area of affect greater than the default 3x3/5x5 throws out all notions of game balance anyway, so the main 'Distance' setting will be good enough for people who want to go bigger.
