Establish better delineation between Node & Wallet about gui

[Sjors]

There's not much utility in running a node without also using it as wallet, i.e. to verify coins you receive. Hooking up an external wallet is too complicated at the moment for a first experience, though hardware wallets are within reach (see #4).

Note that when you first install you're presented with an intro screen that is mostly about the Node side of things. After that you're looking at a syncing blockchain, until you dismiss the full screen popover.

Regarding the Overview tab: it could make sense to add a section with basis node stats. Perhaps the sync stuff that's currently at the footer of the screen, could instead go in that section. That can also make it more clear when the node is fully synced, in case the user is waiting for a transaction to come in.

@achow101 proposed not immediately creating a wallet, see bitcoin/bitcoin#15454

There is strong public advocacy to 'Run your own node' for all the obvious reasons. And many say the easiest way to do that today is 'just download/install core.' Fair enough. But for a new user, that is not what appears to be taking place when you actually install Core. Instead, the UIrominent position is the "Overview" panel.

I guess what might also help a lot, would be if the design of the whole UI would become a from top to bottom style that could easy disp on a mobile, so that we have on desktop and mobile the same style. That would also boost dev to make the UI the pure remote of a full node or wallet.

I believe we should reconsider how "empty space" in the UI can be reallocated to more useful displays of information...

For example the Network tab can be reworked to display more information "at a glance".

If done well the Information tab and the Network tab can be consolidated into one useful "at a glance" display.

This is a quick cut and paste but I think it conveys the idea...

This approach of "at a glance" can be reworked so that the main window can be resized and a "block height" window overlays the window so that the user can see the block height...

This approach would actually obfuscate the balance of the wallet that is loaded...and may be a useful way to create a log back in prompt...which adds a little more security from people walking away from their computers without logging out...

This will also give the user a "widget" type experience similar to having a desktop clock widget..
