closes#6377
- restores ajax prefilter initializer that was removed in #6243
- adds regression test for standard `$.ajax` requests sending Authorization header
This can be removed once we no longer have jquery plugins that make internal ajax calls that don't go through ember-ajax.
no issue
- add ember-suave dependency
- upgrade grunt-jscs dependency
- add a new .jscsrc for the client's tests directory that extends from client's base .jscsrc
- separate client tests in Gruntfile jscs task so they pick up the test's .jscsrc
- standardize es6 usage across client
issue #5751
- moves `makeRequest` override of simple-auth's OAuth authenticator into our own custom authenticator (previously our override was not taking effect until after ember-simple-auth's initial authentication routines, hence why it was working for post-login token refreshes but failing on app-boot)
No issue
- moves the authentication initializer to be an instance initializer
- updates dependencies
- fixes error with asset-delivery not copying
- fixes problem with testing by re-building ember before casper tests
