CB-6715 [webOS] Upgrade webOS Cordova project tool/template

Upgrading for both Cordova 3.x standards as well as for the new backwards-compatible tool, ares-webos-sdk (due for public release in the next few days).  If you want to hold off on integration until after ares-webos-sdk goes public, I'm fine with that.  Tested on Windows 7, Mac OS X 10.9, and Ubuntu 14.04.
