Add nested delegate call warnings

[iamacook]

What it solves

Resolves #3115

How this PR fixes it

Nested delegate calls now display that they are a) a delegate call and b) (un-)expected. They also, like #3091, base their legitimacy on whether the address is known or not.

An unexpected, nested delegate call can be found here.

How to test it

The linked example transaction can be used as a PoC for this new warning.

In order to create another, it needs to be done via a script. You would have to use node.js or propose a transaction.

Screenshots

(The following "parent" delegate calls are "unexpected" because our MultiSend contract is not a known address on Rinkeby.)

The known address name was set manually here in order to trigger the warning:

Can we remove the extra gap and add a gap in the action section?

[francovenica]

I don't have a way to reproduce a tx like the one in the example.
The tx given as example works fine in this PR and shows the warning message so I'm ok with passing this ticket.
@katspaugh Do you think we should try to find a contract and reproduce a similar tx?
