Changed lots of things :P

- Moved THREE initialization to the Client class
- Created a dummy Client Main class to load the scene
- Removed the window's frame
- F12 to open DevTools
- F11 to reload the page
- Added Mootools' server script
- Added a HTML Titlebar with a title and a close button (basic : ugly)
- Begun the move to Mootools class rather than basic JSObjects
