This commit refactor the plugin to properly organize code and make it
easier to follow.
In newer Embers jQuery is removed. There is a `find` but it only returns
one element and not a jQuery selector. This patch migrates our code to a
new helper `queryAll` which allows us to remove the global.
This is long overdue. We had a lot of (not linted) code to initialize
our test suite as part of the Ruby `test_helper.js` bundle.
This refactor moves that out to a `setup-tests` module, which imports
all the modules properly, rather than using `require`.
It also removes the global `server` variable which some tests were using
for pretender. Those tests are fixed, and in the case of widget tests,
support for a `pretend()` was added, which mimics our acceptance tests.
One problematic test was removed, which overwrites `/posts` - this could
break tons of other tests depending on order.
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
