Attach Implements Manually 1.0.0.3

1.0.0.3:
- Added setting and corresponding function for automatic attachment of front loaders. When enabled, front loaders will automatically attach as soon as the front loader is close enough to the front loader console of the vehicle.
- Fixed ineffective setting for automatic attachment of front loader implements.
- Improved overall performance impact of the mod.
- For modders: In the modDesc.xml, it is now possible to specify the path to a configuration file. In this file, AttacherJoints can be marked as front loader AttacherJoints, so that corresponding configs and functions for these AttacherJoints can be used. Documentation of the functions can be found in the sdk folder.
