* refactor asset items to use list-item
Refactors the asset-list-item and token-cell to rely on the list-item
component for UI. Little changes were needed to the list-item code
to make this work! The result should be lots of eliminated code

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.
The asset list has been updated to more closely match the new designs.
There are still a few major differences (e.g. the selection state, the
token menu) that can't be implemented until the asset screen has been
implemented.
The background color of the selected asset has been lightened, so that
it's less jarring until we remove it.
All asset list items now use the same component (`AssetListItem`).
Previously the tokens and the Ethereum balance were totally separate
components, despite being styled similarly.
Various unnecessary DOM elements and style rules were removed, but the
overall list looks identical to how it looked before.
The token cell how shows a warning inline for the case where the token
balance failed to update. It displays a warning icon next to the
balance, with a tooltip that contains the same contents as was shown on
the token list previously.
The styles for the TokenCell component have been moved to be alongside
the component. They have also been renamed from `token-list-item` to
match the component name.
