[account_financial_report] adds the following features to Trial Balance:

- Adds 'Period balance' column
- Renames the option 'Hide accounts at 0'. Means no initial, no debit, credit
  or ending balance for the period.
- Fixes logic to remove lines with 0 activity for the period.
- improve the calculation in the Trial Balance
  of undistributed profits/losses account, and provide a footer note
  to the user explaining why will the ending balances will not be zero, but the
  period's total profit and loss.
- add an extra line for P&L application so that the trial balance zeroes in the
  balance, and total debits = total credits
- refactoring of the unaffected earnings reporting in the general ledger
  and trial balance.
