n#782345 import DOCX w:splitPgBreakAndParaMark compat option

This fixes docx import of page breaks in empty paragraphs, when the
compat option in question is set.

Even empty paragraphs have an "end of paragraph" character in dmapper:
import page breaks there, instead of delaying the import till the
all-catcher importer at the start of the next paragraph.
