Patch notes for Dec 22, 2021

This patch includes the Editor Upgrade, the Winter Challenge until January 10th, and also:

• Tweak distance of Wolfman pounce slightly down again, so it's still easier to cross 2-tile gaps but you won't hit your head

• When there are two Yerfdogs, the second one no longer instantly spits out any inhaled objects

• Spiffy up the forest background ever-so-slightly

• Fix crates sometimes falling through platforms when being spat out by Yerfdog

• Fix bug where portcullises cannot be placed in the editor

• Fix possibility for Frank to push a crate a second time before it finishes being pushed once

• Fix camera calculations so guys don't sometimes float off the ground by 1 pixel

• Fix candy cane poltergeists causing the level exit to never unlock

• Fix a theoretical issue where possessed guys could have sometimes skipped tiles due to their double speed

• Fix Kids emitted by Yerfdog or Witch creating a start marker when they shouldn't
