Need making json export format like redmine standart

[lightinen]

Now keys.json like an numeric array of data like:

[{"id":,"project_id":,"name":"","body":"","login":"","file":null,"url":"","comment":"","whitelist":""}]

But redmine standart json API like

{"keys":[{"id":,"project_id":,"name":"","body":"","login":"","file":null,"url":"","comment":"","whitelist":""}]}

Because of this difference you may have a trouble with extending external libraries, working with redmine rest api

Fixing (vault/app/controllers/keys_controller.rb: line 72):

- format.json { render json: @keys }
+ format.json { render json: { :keys => @keys }}
