v2.14.0

Update to add support for graphql@0.12, and drop versions before 0.11 from the peer dependencies list. The graphql package has some breaking changes you might need to be aware of, but there aren't any breaking changes in graphql-tools itself, or common usage patterns, so we are shipping this as a minor version. We're also running tests on this package with both graphql@0.11 and graphql@0.12 until we confirm most users have updated.
