Update for swipe menu and BBui.js/css

The swipe menu requires the com.blackberry.app plugin as well: issue #994 https://github.com/blackberry/bbUI.js/issues/994

I took the opportunity to update bbUI.js and bbUI.css at the same time.  I did a diff from https://github.com/blackberry/bbUI.js/tree/master/samples/bb10, and skipped all the formatting differences, incorporating only actual changes to the code.  

Would it be better if I copy the two files outright?  There were nearly 700 differences, so it's not impossible that I missed something.  I tried the project out on my Z10, OS 10.2, and it worked fine.  However I am thinking that perhaps formatting differences should also be carried over since the bbUI versions are the same.  I am just uncertain where the "real" version is.
