Patch provided by Annika89

This patch adds support for images inside <v:shape> tags (besides the already supported images inside <w:drawing> tags). InsertDocument method no longer results in a corrupt/invalid document when an inserted document contains an image that is inside <v:shape> rather than <w:drawing> tags.
