Add ability to add account to vault

Scrolling to the bottom of the accounts page now reveals a downward-facing chevron button.

Pressing this button shows loading indication, adds a new account to the identity vault, displays it in the list, and scrolls the list to the bottom of the page.

Any number of accounts can be generated in this way, and the UX feels intuitive without having to overly explain how HD paths work.
