Bug Fixes

A couple of fixes. Big ones to mention are: 

-Now you can smoothly walk against walls. Before you would have some weird bounce or jitter.

-The pred has a decrease in speed and will lose you easier when you lose line of sight.

-Sounds were changed a bits. Sounds in general are less loud if they are made on the other side of a wall and they are even less loud when they are made on a different floor. This is somewhat experimental because it may make the pred harder to hear.
