Small maintenance release to enable usage of newer versions of numpy.

Versioning Changes

• Python-quantities has been updated to work with numpy 1.13, and so now we require quantities>=0.12.1 to ensure we're using the fixed version
• Versioning lock on numpy has been removed, so you can now use numpy>=1.13.0 if you so desire!
