Merge branch 'make_unique' into 'master'
Break compatibility with pre-C++11, implement make_unique @moebius, @lyon - if I understood you correctly, OVM and OM shall also be C++-11-and-up? If so, we can avoid some more ifdef complexity by just breaking compatibility now. (If not, I'll revise my make_unique patch) Let me know if you'd prefer separate PRs. See merge request !13
