PrintLayout: emit progress from printTable()

Browse source 
printTable() now emits a 'signalProgress'
to the PrintDialog's progress bar, but it has 3 stages (loops):
- pupulate a model
- process all rows
- render the table in pages

This requires that we also separate the progress in 3 stages
of 33%.
