tdf#104823: support for sdt plain text fields

This is a squashed commit containing set of changes:
* Create a input field from sdt text block.
* Advanced support for reading field data from data bindings
  which can point to custom xml or properties xml. For this
  XOOXMLDocumentPropertiesImporter idl interface was extrended
  with extra getterrs to get properties as xml dom elements.
* Support for exporting of this feature back to docx. For this
  some extra parameters for sdt block are kept in newly introduced
  grabbag for input fields. If field does not contain grabbag it
  being exported as before (FILLIN or whatsoever), otherwise
  sdt block is counstructed based on data from grabbag.
* Basic support for updating custom xml values back into
  custom xmls with usage of xslt transformations. To achieve
  this extra parameters were introduced to XXSLTTransformer:
  now it is able to support in-memory transformation stylesheets.

* plus some follow-up clean-ups

Some unittests were corrected: since sdt plain text edit area is
a field located inside paragraph in outout corresponding sdt is
also located inside paragraph (instead of Word's approach with
paragraph inside sdt). Seems this is not critical.

crashtesting: set document reference only once

For SdtHelper we need to keep valid reference to main document
(in our case first call), not to any of substreams like header,
footer, etc.
