Additional default OOXML namespace aliases (#97)

The http://schemas.microsoft.com/office/word/2010/wordprocessingGroup namespace is expected to have an alias of "wpg" by LO 6.4. Having a different alias caused LibreOffice to not display grouped drawings.
I copied some additional default namespace aliases from sample files, to hopefully prevent such errors in the future.
