Crop Dropdown!

Hello everyone, after many requests about changing the way the auto replanting works, I have worked out a system that should now be easier! The replant button has now been replaced by a dropdown of all available crops you have so this way you do not have to be trying to step through loops to get it to work.

Additional updates:

- Farmers now have the crop they just planted appear above their head when they re-plant something.

- Displays more accurately "Weekly Wage" instead of "Daily Wage" for farmers.

- Tweaked the max event increase.

Hopefully one of the last bugs patched up:

- Max plots research is fixed. There were a bunch of logical issues with that that have all been patched out.
