... and don't modify standard frame styles to have no borders and padding.
This makes "Frame", "OLE", and "Graphics" frame styles of imported DOC
files to have usual settings (for "Frame", it's 1.5 mm padding and all
borders set to 0.05 pt black line).

All objects that need invisible frame will have them with all necessary
settings set explicitly, which allows to copy and paste such frames to
other documents without problems.

This makes DOC import aligned with DOCX import in this regard.
