Fix html importing and add extra tests. 🚩

Fixes some possible import errors when in a nested route. I've also added some tests to ensure correct html importing.

Auto element importing! 😎

Automatic element importing based on installed bower packages with web-components keyword and having a valid html import file. 👍🏻 Now all that's needed to install and use an element is a simple bower install command like so:

bower install PolymerElements/paper-button --save

The rest is magic. ✨

Also,

• Updated ember to v2.9.0
• Update dember-cli to v2.9.0
• Refactored config handling in addon
