ASSD - Ho(s)tel Management Software PMS 3

Letters that are created via control fixed dates can be saved in the reservations documents as PDF.

This requires a node server to create reports (c_code report_srv).

As in PMS2, it can be configured at position 5 in the letter whether it should be saved.

In addition, creating a reminder can now be reversed directly, but only before the page is refreshed.

Then the old dates are restored and any saved documents are deleted.
