(fix) convert hyphenated module name to camelCase

Before, yo ng-poly:module my-door would create 'my-door' in
app/my-door/my-door.js. Now, it creates 'myDoor'.
(fix) change platform exclude to webcomponents

Before, gulp/test.js excluded platform from being injected in
karma.config.js. Now, platform is excluded.
