1. Primary sequence now can be printed if it has pages inside. I included
   this possibility in the third item of the main menu "All problems
   plus any pages or html/xml files from "Title"". The reason of this -
   page can contain any html or xml documents inside. But I still do not
   understand - either I have to include printing pages in the second item
   of the main menu "All problems from "Title"", because page can be
   constructed from the problems only.
2. I removed any possibilities for infinite loop from the printing of primary
   sequences (second and third items of the main menu). The same I'll do for
   the printing of the assignments for the students and for the printing of the    whole course.
