List to do:
1 no check game over
2 no check if the specific moving is don't trigger shift and merge, so don't add random number
3 random add number not optimize
4 any moving need to check if it trigger shift() and merge()

List done:
1 v1.0 version is finished, there are some bugs need to fix
index.html
1 using bootstrap and jQuery
2 need to add div animate

style.css
1 a lot of fixed height and width need to optimize
I new 2048.js and index.html and style.css in my local file in advance, so I need to initialize a new github repo
with README and LICENSE files.
Merge branch 'master' of github.com:qzTW/2048
