So we have two solutions:
1) set the Buffer again for pars_[pit] and pars_[pit - 1] and do this
for all operation that involves a Paragraph or an Inset copy.
2) set the buffer for all paragraphs and insets in updateLabel() as this
is guaranted to be be called each time each time a new Paragraph or a
new inset is created or removed.
3) store inset parents, instead of buffer pointers, buffer() is the
buffer stored in the outermost InsetText. Swapping paragraphs within the
same InsetText/Text would not even have to adjust anything.

So, Paragraph : Inset ?
