Feature/private comments

[codemoe]

Adds a "private" boolean column to the comments table

Adds a checkbox to select if the comment should be private and a send button (Because if you click on the checkbox, hiting enter won't submit the form).

Private comments are marked by a closed eye icon on the right bellow the sponsor icon

The private comments can be seen by a user with admin privileges and the document sponsor. A user is able to see his own private comments,
