text: Title: [feature] Use a chrome plugin that can both add the site and the cookies that were used at the time (keep the login etc)
  Body: **_TLDR - A chrome extension that can add a URL to your cdio install as well as store the cookies used._**
  
  So from working on https://github.com/dgtlmoon/changedetection.io/issues/2197 , it turns out that setting cookies is more complicated that just setting the `cookie: xyz=1` custom header field, it is also 10)% necessary to enter data like "expires, httpOnly, domain" etc, which is kind of 'meta-data' to the cookie that is not actually set in the "cookie" header field.
  
  So I found this https://github.com/kairi003/Get-cookies.txt-LOCALLY
  
  I was thinking that this could be forked to push the current URL and cookies to your changedetection installation at the click of  a button using the existing API. 
  
  With some little hack it could be made to recognise the "api settings" page and automatically setup the API token, you just have to locate to the config page
  
  This would also solve one piece that is missing, which is some chrome button to add a site to your watch - however setting the actual "Visual selector" should still be done (for now) in changedetection, but that could be an easy addition in the future to the chrome extension
  
  Another idea is that it could also be told to set the mode to simple 'change detecting' or 'restock detection' etc
