Resources and Accounts Fiat worth

[GhenadieVP]

Now Wallet displays the Fiat worth for each particular resource as well the Account total fiat worth.

What has been done

• Introduced the TokenPriceClient to retrieve the prices for each token. Currently only USD is available.
• Used the new client to calculate the Fiat worth at the moment of composing the AccountPortfolio.
• Updated how Stakes and Pools are loaded -> now those are fetched in the background as soon user lands on home screen. This is needed, so that we are able to calculate the Account's total Fiat worth, + the total fiat worth across accounts.
• Integrated the logic for showing/hiding the fiat value, by reading and modifying the respective Profile field.
