Add ability to select display currency on wallets page

[JamesSmartCell]

Select between fiat or crypto value.

So, it would work a bit like Metamask - when you change the network you see the balance in that network.

Hi @JamesSmartCell Can you give some screenshots to describe what you want?

On wallets page, it shows fiat as summary balance.

For meta mask, it show both fiat and crypto balance at the same time, and users can choose which is the primary one.

Should get @colourfreak's input on this.

What I want to do is be able to see the crypto balance of my wallets, for any specific network including testnets.

Example: we work across many testnets and mainnets with maybe 20 accounts. If I'm working on say Cronos testnet and haven't touched it for a few weeks I want to find which wallet I put it in.
