Update to version 0.3

• Added aisle markers and department signs throughout the store.
• Increased the speed of opening bakery cabinets and freezer doors.
• Rotated some produce items on the shelves for better visibility.
• Added a couple carts around the store that you can bump around.
• Lowered number of shoppers in line to 3.
• Increased the visual number of shoppers by using more of the material variants and mix/match hairstyles
• Added extra shoppers that wander the store and head to the line when it is their turn.
• Added sounds to the shoppers when the player bumps into them.  Credits to "aderumoro" and "theuncertainman" from freesound.org
• Redesigned pause menu.
• Added settings menu to adjust the music and sound effect volume.
• Added local high score that displays on game over.
• Tweaked scanning system that after a certain number of items, the bonus for each item scanned decreases, before eventually going to 0.  This way it is essentially impossible for a game to last forever.
• Rearranged flowers to (as much as possible) put the same color of flower in the same position. e.g. All white flower varieties in the top left.
• Renamed "Orange" flowers to "Peach" and "Lavender" flowers to "Purple"
• Decreased time for products to disappear after scanned at the checkout
