Clicking for pillows and sticky hand

Updated Character Controller and GrappleHook scripts to allows players
to left click to place pillows and right click to throw out the sticky
hand. Updated where the sticky hand starts at from the player based on
the mouse position. Updated instruction screen with pictures for sticky
hand and pillow placement, updated controls, and sharper text. Made the
instructions screen stay up longer as more text is there to read.
