move dapp up to Intern 2.1.0, and cleanup testcases. Made updates to some tests to be skipped on FF and IE, I added FF to run on saucelabs, but still have issues on IE on saucelabs even though tests run on IE on my system. Also removed use of dojo/json, switch to use decor/sniff and removed some has.add calls for requirejs which were not needed, and some tests needed a call to deliver() to get initial values set.
update to dapp to use delite 0.4.0-alpha.2, deliteful 0.4.0-alpha, and requirejs-dplugins 0.3.x. Along with move up to intern2.1.1
fix bower conflict with requirejs-dplugins 0.3.x for travis build.
Add dapp unit test for deliteful/ResponsiveColumns.
fix jshint errors for travis build.
