Patch: Add move-constructor and move-assignment-operator for PermutationMatrix and Transpositions

I realized that the classes PermutationMatrix and Transpositions could
not be moved.

The reason for this is the definition of the copy-construnctor but not
the corresponding move-constructor.

Please find attached a patch which defines the missing move-constructor
and move-assignment operator for PermutationMatrix and Transpositions.

Of cause the additional move-constructor and move-assignment operator
are only activated if EIGEN_HAS_RVALUE_REFERENCES is defined.

Comments to the patch are welcome.
