this fix should restore the old copy/paste behavior in calc and still
only paste relevant entries to external programs

This reverts commit bbad7057.

These have type positiveInteger, so don't write 0 values:

20.191 fo:hyphenation-push-char-count
20.192 fo:hyphenation-remain-char-count

The following 3 attributes have been added in ODF 1.2, so don't write
them into ODF 1.1 files:

style:layout-grid-base-width 20.297
style:layout-grid-snap-to 20.305
style:layout-grid-standard-mode 20.306

Additionally, style:layout-grid-snap-to was written wrongly as
style:layout-grid-snap-to-characters, which does not exist in any ODF
spec.
For backward compatibility with previous OOo/LO versions, write the
wrong attribute in addition to the correct one in ODF extended mode,
even though validators complain about it (consider removing that
some years from now).

Fix a problem with empty paragraphs, that previously did not get
proper end-of-para / end-of-line markup, thus the slideshow mis-
counting them when getting index-based animation targets.

String compare was not replaced equivalently, this needs matching
against the XTEXT prefix, not exactly

Removed VERBOSE_TEXTCOMMENTS exporter flag, that's now unused.

Added some verbose-mode trace output

Revert "aw084: #i108052# Added code to mimic old behaviour and call user layout link when empty paragraph is rendered"

This reverts commit 9d40293f.

The change was causing extra paragraph markers to be emitted, e.g.
leading to fdo#43837 and fdo#43684.
