Review Request: libs/vectorimage

[Stuart Dickson]

A single library for managing EMF, SVM and WMF files.

I have submitted commits to the branch: libs-vectorimage-stuartmd-forreview
Only the last three are relevant to the libs/vectorimage work - the diff 
may be generated with the call:
git diff c55ec6499c5ead6d6a9b434651ab31f92d8b0b8b


In reviewing master branch, it was determined that the problem building 
the epub export filter lay in the way it was trying to use the vector 
image libraries already present in plugins/vectorshape and filters/kolibwmf.
(This problem may have only really manifested on Windows, owing to the 
way it handles shared libraries).

There had already been a suggestion that, as there was already some 
awkward coupling of plugins, and filters and knowledge of the location 
of the sources required, that moving the library code for EMF, SVM and 
WMF vector file formats into their own library would be the best way 
forward.

This patch creates the library and makes the necessary changes to its 
dependents and has been tested to function on the Windows platform.

Stuart
