Correct comment behavior with optional notifications

This allows submitting comments with and without notification
for the created journal.

Using hyperagent resource on activities, the resource `addComment` is
replaced when executing `fetch` on the link.
This breaks subsequent comment requests. This is fixed by requesting
manually on the resource link using `$http`.

This commit also provides the functionality required to comment with or
without notification propagation, and changes the backend to comply to
the APIv3 specification, which defines comments to be sent as a JSON
`{ comment: { raw: 'my comment' } }`.

This commit also provides:

* Displaying the comment input on overview depending on sort setting
* Disable inplace controls when comment is empty
* correctly hiding the comment based on link availability
