Follows the previously set pattern of colocating styles along side the
consuming components. This one was really straight forward and just a
reorganization of files and imports. No code changes occurred.
The old tooltip component was only used in two places. Removing those usages
was simple and straight forward. So, instead of colocating the old tooltip
styles with the deprecated tooltip component, I removed all old styles and
made tooltip-v2 now simply 'tooltip' and removed the deprecated component.
The 'copy-to-clipboard' icon was removed in #8190, and replaced with a
new 'Copy' icon component. It was still being used in two places
though, on the confirmation page for decryption and on the reveal seed
phrase screen..
The new Copy icon is now used in these two places instead. It has been
given a size of '17' to match the old icon size.
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.
Implement `eth_decrypt` and `eth_getEncryptionPublicKey`. This allows decryption backed by the user's private key. The message decryption uses a confirmation flow similar to the messaging signing flow, where the message to be decrypted is also able to be decrypted inline for the user to read directly before confirming.
