A new page has been created for viewing assets. This replaces the old
`selectedToken` state, which previously would augment the home page
to show token-specific information.
The new asset page shows the standard token overview as seen previously
on the home page, plus a history filtered to show just transactions
relevant to that token.
The actions that were available in the old token list menu have been
moved to a "Token Options" menu that mirrors the "Account Options"
menu.
The `selectedTokenAddress` state has been removed, as it is no longer
being used for anything.
`getMetaMetricState` has been renamed to `getBackgroundMetaMetricState`
because its sole purpose is extracting data from the background state
to send metrics from the background. It's not really a selector, but
it was convenient for it to use the same selectors the UI uses to
extract background data, so I left it there for now.
A new Redux store has been added to track state related to browser history.
The most recent "overview" page (i.e. the home page or the asset page) is
currently being tracked, so that actions taken from the asset page can return
the user back to the asset page when the action has finished.
This changeset updates the `getOriginOfCurrentTab` selector and the container
for the ConnectedSites page to use `activeTab.origin` instead of parsing the
URL. The `activeTab` URL is parsed in `queryCurrentActiveTab` before the UI is
launched and any subsequent parsing of the URL is unnecessary.
See `queryCurrentActiveTab` in `ui.js:86` [1].

This change replaces `getRenderablePermissionsDomains` with a new selector `getConnectedDomainsForSelectedAddress` that works better. The data returned from this selector is used to populated the _Connected Sites_ modal, which (as of #8262) didn't use most of the data returned from the old selector.
The old selector only looked at the first address that was exposed, making it not work for anything other than the first account connected to a particular origin.
