The main changes are:
1. Translated all resources in the database. All the blocks have 2 copies: One is for eng and the other is for zho.
2. Add _YQQ for persion info. _YQQ indicate the Tencent QQ (<a href=http://www.tencent.com/>http://www.tencent.com/). It's an Instance Messager that is very popular in China.
3. Full install scripts translate. There're some language resources in gui.php that not include in global.php. I've added it.
3. Some other fixes.
