Trying to automate the login into a Google account is quite hard. This makes the crawler use the content of a cookies.txt file instead. It also removes a couple of deprecation warnings and adds some color to the output.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
