Remove non-copyable idioms

Browse Source 
Two better ways of making a class non-copyable in C++11:

* Store the p. impl. in a unique_ptr (for the cases of classes with p. impl.),
  or:

* Define publicly the copy constructor and assignment as deleted

Lots of other classes could be cleaned up in this way.
