HW4: Now able to deployed to App Engine

Just resolved the “Error: NOT_FOUND” problem by adding welcome-file-list
in war\WEB-INF\web.xml. Not it runs successfully.

There's one problem so far, after one player won the game by capturing
all the other player's pieces, attempt to change the player may cause
the browser crush...

Other than that, the game runs fun. (Selected piece should better be
highlighted... And need to add a image of translations for the pieces
since it's chinese charactor on each piece. I will add that later...)

Special thanks to my girlfriend joyce... For providing me all the images
囧...
