Scrollable home page & inline transaction detail view

[bdresser]

We've introduced several different floating or sliding elements in to the extension, most added individually, and the modal transaction detail view & slide-in "speed up" component make for a very awkward transition. This issue aims to simplify UI treatment of a couple new elements:

We should

• make it so that everything from the account nickname and below scrolls together. That includes transaction history, overall ETH balance, overall fiat balance, deposit/send buttons, and token/ETH logo. The bar with hamburger menu, account bar, and account ... options should be fixed.
• show the transaction detail view inline (as it's shown in the full-tab view).
• remove that tiny line on top of the transaction history because we don't need it and it will make @cjeria very happy 😄

@bdresser Just to confirm, bullet point 2 is referring to removing the flow of opening up a modal with the transaction details and using the expanding behavior of the full-screen view right?

@alextsg correct - like it used to be in your first iteration 🙈
