* code cleanup on autofarm.cpp
* more code cleanup on aufofarm.cpp
* yet more cleanup of autofarm.cpp
mostly whitespace, some `*` and `&` adjustments
* downgrade autofarm to c++11
apparently the gcc we use doesn't support c++14 generic lambdas
* death to whitespace
apparently visual studio's default whitespace murderer doesn't touch `#define`s. who knew?
* Update autofarm.cpp
const is good
Update autofarm to count PLANT_GROWTHS as well as PLANTS for threshold purposes. This addresses #1902.
Also addresses some pointer hygiene issues in autofarm.
