Better notifications, quality and bug fixes

The latest build of the demo is now up! Thanks again to everyone who have provided feedback on the demo so far! It's really great to get this kind of response, you're awesome! Here are the latest changes based on your feedback so far:

• Added an audio + visual notification when research is finished so you don't miss it.

• Also added a notification for when the Hipster types are changing and when there's a new hot topic trending on Tooter, so its easier to pay attention to the trends in the game.

• Increased the smallest Latte art brush, and slightly improved the AI that is attempting to recognize your latte art drawings. This actually an extremely complicated task for the computer, so it's not perfect, but it should be better than it was.

• Menus now close when you click on 'nothing' outside of them.

• The staff info panel now lets you toggle on / off the skills on each staff.

• Fixed Audio for Voice / Interface not being affected by Master Volume slider.

Plus a bunch of smaller bug fixes.
