Export page as .csv

[weidemann]

PCF used the title and page number in combination to name the exported file. Page numbers are very useful to go back and edit something. However in double digit numbers the last digit is dropped. As such for page 1 it will produce "title #1.csv" and for page 10 also "title #1.csv".

For ordering in folders the page number could be first, the filename followed by the title.
