Enabled auto user creation and special admin login page

### Admin stuff

First, create and access token
`export SIMPLECMS_ADMIN_TOKEN="some_random_token_generated"`

Login admin through
`URL/adminlogin?access_token=<your_token>`

Create admin user from rails console

### User

User will be created upon visiting any valid URL without access token, check the code on how users are named / numbered.


Actually don't have to worry too much about this. It is very unlikely that they find the signout path AND know that they have to send a DELETE request AND know where to get the valid CSRF token.
