oox: import Math objects from PPTX files

Desktop / LibreOffice - Michael Stahl [redhat.com] - 21 January 2016 12:42 UTC

This is quite hacky and limited: in OOXML these are not OLE objects but occur inside text boxes, and PPT 2010 allows inserting multiple Math objects into one text box but Impress does not have as-character anchored objects, so we can't import that properly; for now only import Math if there is nothing else in the text box.

Also for now only import them as children of TextParagraphContext (a:p); it's not clear what the possible parent elements could be since the OOXML standard only lists WordProcessingML parent elements :(
