Add the admin UI needed to restore the hidden proposal notifications
when hidden by moderator. The admin can restore them or confirm
the moderation made by moderator, just like proposals.
The little menu with the hide notification link and block user link
has been added to each proposal notification.
JS for adding the fade efect has also been added.
Add new routes for the proposal notifications edition and
abilities to let moderators edit it (mark as ignored, hide, etc.).
The notifications are not flaggable because they doesn't work like that,
but in a similar way. The moderator/administrator is in charge of hidding
them through the UI, so the normal users don't flag it as inappropriate.
New controller Moderation::ProposalNotification to manage the moderators
work.
Move the button so that it appears in the Winners tab of the
budget_investments index.
When the budget is in "Balloting projects", "Reviewing Ballots"
or "Finished budget" phases, the button will appear as a button
(clickable). If there are no winners calculated yet, the text
will be "Calculate winner investments"; if there are, the text
will be "Recalculate winner investments".
If the budget is in another phase, the button will be
disabled and a message will appear: 'The budget has to stay on
phase "Balloting projects", "Reviewing Ballots" or
"Finished budget" in order to calculate winners projects'
To delete a translation, a link has been added. This
link works for the selected language. It hides all the
things related to a language (the tab and the text_area)
and empties the text area, so that the value is blank
in the param hash. A variable called `delete_translations[]`
is changed.
e.g. If admin wants to remove English language,
delete_translations[:en] will be 1; if not, it will be 0.
When the milestone is updated, there is a before_action
callback that cleans the selected languages for deletion
(looking the delete_translations[] variable).
Because of the deleted translations are blank in param hash,
them won't be saved in DB.
