Some small Fixes

Hi,

This fixes a bug on mobile devices were the wrong definition of SHOW_ALL was used.
It also changes the paths of phaser.js and main.min.js to allow the project to be in a subfolder.

Having / at the beginning if the path forces the user to place the whole game project in the root folder of the url.
E.g. example.com. Putting it to example.com/mycoolgame/ will result in an error.
