Game's running

The big update made during the DemoJS event.

HTML/CSS:
Added Meyer's reset.css
Remade half the UI in CSS for easier manipulation.

JS:
Reorganized all the game code in classes.
Made a working game engine with a loop to handle game logic. Game UI is
still managed by EaselJS.
Added a latency compensation system from the one in Cookie Clicker.
Added jQuery 1.11 to the project, plus a plugin to add more easing
functions for animations.
Added a neat animation when you click on the Clicker.

MISC:
Rewrote the comments in English. Game text is still in French though.
