feat(gnodev): txs manipulation ability

[gfanton]

This PR adds the ability to manipulate transactions:

• Users can cancel and redo a transaction from the terminal UI using the P and N commands.
• Users can save the current state from the terminal UI using Ctrl+S and restore it later with Ctrl+R (reset command).
• Users can export the current state in a genesis doc format from the terminal UI using the E command.
• Users can load and extract transactions from any genesis file using the -genesis-file flag.

~TODO:~

• [x] Add documentation.
• [x] Add unit tests.

@deelawn Good point. I will merge your PR (#2281) and then rebase this one on it. I will then update this PR so genesis-file also loads genesis balance, and let it be overridable by txs-file and/or balances-file.

[gfanton]

Thinking more about this, I believe we should not authorize balance-file and/or txs-file along with genesis-file, as it would make things more complex and is likely not very useful. If we find a use case for this in the future, we can revisit and rework this part.

Waiting on @leohhhn to update the documentation

@gfanton Just a nitpick, not all of us are fluent in Amino binary :)

[gfanton]

@zivkovicmilos I will updated this in a future PR. At the moment, it doesn't take into account the type of the event and just logs it with a %v. Improving gnodev log is definitely on my to-do list :)
