Lightening up [0.2.12]

This version contains some small but important tweaks:

• Add the missing commands to Drop items to the Action Menu
• Allow toggling tips instead of disabling them completely
• Improve onboarding sequence: use [Ctrl] instead of enter, put additional info about building fences, raise the order of the Actions menu, and put the “hide tips” shortcut at the end
• Allow dropping floating things in the water (so you can now push a raft into the lake and paddle)
• Add a message when extracting seeds from a plantable
• Prevent the sudden disappearance of animals when you don’t see them
