Merge pull request #5 from whywhy36/lungo_ui

Lungo ui, this is one big change to this project, use lungo ui instead of jquery mobile, there are still some bugs for the lungo. Lungo's history track seems some problem, so it's better to use programming router instead of the built-in html router. After fixing some bugs and backend issues, this pull request will be merged now.
