[1.4.8] Show total balance / remaining budget of each month / year in period selection view

@Fabian

This post is set on „completed“, but:

I would find it great if I had an overview of how high the account balance of the considered account is after deduction of all planned (individual or regular) debits before the next salary is received on a date I have set by myself, almost a "if I have paid for all this, I still have so much left for shopping, partying, eating out before I get money again".

If the app already gives this: please tell me where I can find it. Thank you.
