* minor clean up, some help text and links

* remove icon from list update popup

* show added/removed tokens

* add GA everywhere, don't debounce contenthash lookups

* increase timeout to maybe fix integration tests which pass locally

* build for tests using the dev network url

* reset the lists if we deleted the other two copies

* improve how we handle updating the default list of lists

* fix integration test

* Update token list selection styles

* fix external links, reuse the on click outside code, show add errors

* show the list origin instead of the full url

* fix update list link

* show host instead of hostname
do not automatically dismiss major version upgrades for lists
