EMF image support

[eruffaldi]

This patch allows to add EMF images. EMF contains size in 0.01 mm units, so I have picked 300 DPI for computing pixel size.

Provided also a sample script with EMF for testing

As you described it it doesn't work for me. I had to change the signature offset (image.__init__.py) to 41 instead of 40. After this minor modification it seems to work just fine. Great addition, thanks!

Anyone waiting in vain on this and needs EMF support without having to handroll their own patched version of the docx lib can try this monkey patch version of the PR code:

Works wonderfully so far! Thank you. Hope this can one day be added without patching.
