[messages-inforable-3] Add checkboxes to infotable (Privátní)

Add checkboxes, which articles will be send to payment. By default checkbox is unchecked.
- When checked and clicked to Payout, these articles will be sent to payout.
- if article was already send to payout, there will be no checkbox/or will be unavailable

Some old articles aren't visible, because they are too old (or there are more than 50?), what will happen with them? They are already paid.

Důvod/vzkaz

• checkbox isn't needed, when we don't want to pay anything, just insert 0
