The styles that defined the `account-panel` component now belong to the `panel` component, which is now used by the `account-panel` component for its styles.
It accepts an optional `onClick` property that it will fire when clicked!
Planning to use it for the tx-list.
Account detail view now has an animated transitioning `subview` section that allows us to show extra details within it.
Clicking `export` now slide replaces the transaction list with the export UI.
Added cancel/done/submit buttons to the Export UI. Done submits like Enter did, the other two transition back to the transaction list.
For some reason when first unlocking, the selected account is being instantly replaced with the accounts list, so I need to fix that before merging this into master.
