Adjusted documentation of PrintableReport
PrintableReport no longer provides the formatted report as QTextDocument
but as plain QString (so that the caller can decide how to deal with the
text)
Added Print... and Print Preview... actions to main window
Added PrintableReport responsible for formatting of ErrorItems and
exposing of a QTextDocument that can be used for printing
