Update 10 - Moar goals, maps & tutorial

In this exciting update a ton of new stuff awaits  the player!!! Woohoo!! Nice! Good job! Moar!

For example 2 new maps that act like a tutorial. The game doesn't start with them, because I fear some people might miss the buttons for the levels on the bottom of the game. 

Maps can now have more than one goal. Only the "Match Three" map is using it. 

Slightly changed the background color. 

Instead of complicated to understand points, the maps show the amount of turn you needed so far. The less the better!

A lot small UI changed. The goals are now in the top middle, the name of the map is more subtle in the upper right corner. 

Implemented the first step to unlock levels and worlds. 

Tried to fix the sound issue on some browser/ OS combinations  but not sure if this works.
