copy constructor is implicitly deleted because 'OutputArchiveBase' has a user-declared move constructor

[andrewkcorcoran]

db6586e changed the move constructors and the move assignment operators of OutputArchiveBase and InputArchiveBase to be user defined instead of = default. As a result the move constructors and assignment operators of all dervied classes have been deleted as ... "If the class definition declares a move constructor or move assignment operator, the implicitly declared copy constructor is defined as deleted".

This prevents users from using std::move on all archives!
