Explicitly add move constructor/assignment operators.

These are needed due to some obscure rules in the standard
about how std::vector selects between copy and move
constructors, which can cause a conforming implementation
to attempt to select the copy constructor of RuleMatcher,
which will fail since std::unique_ptr<> isn't copyable.
