Soft delete issuables
Fixes#2489
What still needs to happen: research on the indexes, the gem suggests a [lot of changes](https://github.com/rubysherpas/paranoia#about-indexes) though this is probably a good idea to discuss and I'm unsure on the impact of an omnibus upgrade as I suspect creating about 10 new indexes has a large impact on the downtime.
TODO:
- [x] Also group owners can ***soft*** delete
- [x] Button should be hidden
See merge request !2982

Closes#3024
See merge request !2831
1. Make the "subscribed" text in Issuable sidebar reflect the labels
subscription status
2. Current user mut be logged-in to toggle issue/MR/label subscription
Safari 9.0 does not yet honor the HTML5 `origin-when-cross-origin` mode,
and it's possible load balancers/proxies strip the HTTP_REFERER from
the request header. In these cases, default to some default path.
Closes#3122
Closes https://github.com/gitlabhq/gitlabhq/issues/9731
write_ was renamed to create_
modify_ was renamed to update_
So now in update action we have next code
def create
can?(current_user, :create_issue, @issue)
end
def update
can?(current_user, :update_issue, @issue)
end

Make the Markdown parser recognize "[x]" or "[ ]" at the beginning of a
list item and turn it into a checkbox input. Users who can modify the
issue or MR can toggle the checkboxes directly or edit the Markdown to
manage the tasks. Task status is also displayed in the MR and issue
lists.
Issues filter by description
In Issues section of any project there is a filter box, which by default says 'Filter by title or description' - so this behaviour is desired. But in fact only filter by title works and filter by description DOESN'T work. This fix adds description fitlering.
The goal of suych refactoring is to get rid of observers.
Its much easier to test and code when object creation and all other
related actions done in one class instead of splited across observers,
callbacks etc.
