Stubble Cultivator FS2013 v1.1

The goal of this script is to distinguish stubble cultivator and standard cultivator.

choppedStraw mod should be installed in the mod folder and used map should be choppedStraw ready.

This script is a global mod that is added automatically to any Cultivator spec tool.
A new key (LCTRL + 8) allows to switch between Stubble cultivator and standard cultivator.

When stubble cultivator is on, field is cultivated but a choppedStraw layer is kept/added.
When it's off, standard cultivator is applied.

New in v1.1:
-Compatible multiplayer (tested with TSF Team)
-Bug fixed. chopped Straw layer was seen even when the tool was not lowered
-Stubble cultivator can now be activated at any growing stage of the culture

Known issue: Field cannot be cultivated using helper after having used stubble cultivator since field is already seen as cultivated.
