Feature: ability to queue transactions

[stackcryptos]

When trying to send a transaction if the previous one hasn't been confirmed, Kukai will show the following error:

Given the current block speed of Tezos (30seconds) it can be quite frustrating to have to constantly wait for a tx to be confirmed before doing another one (eg: when trying to collect different NFTs, managing farms on two different projects, doing several unrelated swaps etc.)

All major ethereum wallets allow you to queue transactions and it is a fairly common features amongst major blockchain wallets and as far as I know the Tezos CLI also allows you to do it.

This feature would greatly contribute to the competitive advantage of Kukai as a wallet and would give a positive image of the Tezos blockchain for new comers, helping grow the size of the Tezos community.

Sorry for the late response. There's not much we can do in Kukai while run_operation and injection/operation uses different contexts. Please see #376 for more info about this issue.
