WIP: Upgrade dependencies

[bjornharrtell]

Just can't stop upgrading... known blocking issues to be resolved:

• Assertion Failed: You attempted to define a {{link-to "category"}} but did not pass the parameters required for generating its dynamic segments. Assertion Failed: Attempting to inject an unknown injection: 'controller:category'
• Assertion Failed: You modified "crate.owner_team" twice on <cargo@model:crate::ember584:libc> in a single render. It was rendered in "template:cargo/templates/crate/version.hbs" and modified in "template:cargo/templates/crate/version.hbs". This was unreliable and slow in Ember 1.x and is no longer supported. See [Glimmer 2] "Backtracking re-render" is now an assertion emberjs/ember.js#13948 for more details.
• Assertion Failed: You modified "crate.keywords.isPending" twice on DS.PromiseManyArray:ember585 in a single render. It was rendered in "template:cargo/templates/crate/version.hbs" and modified in "template:cargo/templates/crate/version.hbs". This was unreliable and slow in Ember 1.x and is no longer supported. See [Glimmer 2] "Backtracking re-render" is now an assertion emberjs/ember.js#13948 for more details.
• TypeError: Cannot read property 'destroy' of undefined
  at Class.willDestroyElement (copy-button.js:50)

Also, ember-data was downgraded at some point from 2.13 to 2.12. Not sure what the issue was or if it might be resolved in 2.14.

@bjornharrtell You may want to try this new version of ember data which may fix those two "modified twice" errors.

Unfortunately, I think the other two errors are unrelated :P

Closing due to inactivity and conflicts. Ember itself has been upgraded in #1180.
