Ability to specify where money is flowing to and from through the use of accounts

[el3akrout]

Hello @emavgl,

First of all thanks a lot for Oinkoin and your continuous improvements!

One thing I found a need for is to have an accounts tab to keep track of where money is and where expenses are deducted from.
I don't have experience with flutter so I made myself just a working prototype to handle my specific use case. You can check the (most probably shitty) code here.

Here are a few screenshots of what it looks like in the app.

Some decisions taken regarding the accounts:

• Transfer between accounts is shown as two flows that do not impact the balance.
• Expenses and incomes that do not have an account specified are not reflected in the accounts tab balance.
• A default account can be specified in the settings and is automatically chosen when adding an income/balance.
• An initial balance is set to an account and is not reflected in the home balance. An income record needs to be added with the account chosen to be reflected. This eases backward compatibility.

I hope you find this interesting and helpful. I would gladly help with developing this feature properly if you find it useful at some point in the future.

Thanks again.
