Backend and frontend protection against csrf attacks:

- root resources changes the csrf token cookie everytime it is loaded, in particular during the intestitial load during login
- it will also add that cookie on single user mode
- initialize will still load all resources
- but they you cant access them if the csrf token do not match
- all ajax calls needs to add the token to the header
- non ajax get requests do not need xsrf token validation
- non ajax post will have to send the token in as a form input or in the content
