- Only use old hash style
  - Don't replace the aspect ids list with an empty array if it's nil

  - Load aspects stream if user is on this stream instead of loading the
    activity stream

Flash error is shown on bookmarklet post error. On error, return post_something message to form

Now we close the publisher on submit and reopen it on error. The spinner is shown while submission is in progress. Fixes #4949

Fixes #4949

* Wrap it into a transaction
* Use destroy over delete so dependent destroys get triggered
  and we thus don't fail on the foreign key constraits
* Check if a photos status message actually exists before accessing
  it
* Add missing dependent destroys

Thanks to Josias for the hint

.html does not escape any html input in these, leading to XSS
attack vectors.

Fix issue #4964

refs diaspora/diaspora#4959

* added temp. default values for user_id and item_type
* changed model validation for item_type

* changed button description
* replaced links with buttons

fixed:
* comment-report-icon will not be displayed when post author is current user
* if you hover a comment all report icons will be displayed

* changed user_id type to integer
* renamed post_id to item_id
* renamed post_type to item_type

Instead of checking the status code I am using success and
error callbacks from model-save. In that case we have to return
json in the controller for signaling that the request was sucessfully.

Podmin can see a extra checkbox in Settings > Account
for disabling report-email-notification

* join the conditions of the inner ifs
* add a uniqueness constraint to the model
* differentiate between author is a local or a remote user
* simplify controller/mailer functions
