Feature request: basic integrity check

[GfE W3vHy]

After months of "correct" daily use, I also have encountered miscalculations as described in https://bugs.launchpad.net/financisto/+bug/804104 .

I am perfectly aware that this software comes without warranty etc. There is noone (but me) to claim if my decisions are based on wrong numbers.

On the other hand, recalculating totals and running balances on each startup might be overkill.

It would, however, be great if financisto did some integrity check. A very quick and simple one that comes to mind is:

Whenever financisto is started, compare all totals with their respective running balances. Iff they do not match, show a warning and allow to recalculate them.

Two related improvements:

1. provide some means to manually trigger the suggested integrity check

2. make the "totals" button (in the lower right of blotter views) recalculate both, the account's total *and* running balance.

Backup then restore helped me to correct errors in running totals.

Please note that this feature request primarily focusses on the question:
"HOW to make sure the user will recognize (and then repair) such errors in time, so s/he is less likely to base desicions on wrong numbers?".

"Backup then restore" is an answer to a different question, which is:
"WHEN the user has (accidentally) spotted one or more errors in running balances or totals, what can s/he do about it?" (see #804104).
