Adjusted Collisions Update — Blockhead 2D Steam update #1308930

Full notes: - More objects are able to be walljumped off of, increasing freedom of movement across the level. - Beanstalk is now just a border that cannot be climbed on. - Roof was made inaccessible due to it being tedious to cross. Instead, a window was placed at the opposite end of the house to gain access to the backyard.
