* Fix a couple of issues related to the recent cache friendly products

Browse Source 
* Improve the efficiency of matrix*vector in unaligned cases
* Trivial fixes in the destructors of MatrixStorage
* Removed the matrixNorm in test/product.cpp (twice faster and
  that assumed the matrix product was ok while checking that !!)
