[boost] [shifted_ptr] STL support: 99%

Ok, this is awesome.  Last week I made changes in the Sandbox I had to 
revert and rework all over... Now the changes I made in both the pointer and 
the STL containers are clearly to ones I want to stick with.  This brings up 
interesting concepts at the same time, such as: what should be the right 
parameter of allocator::deallocate() ?  We can't use a raw pointer over 
there.  We can see the non-official patch inside the bits folder and 
shifted_allocator.hpp which I think solves the problem correctly. 
Furthermore allocator::allocate() I beleive shouldn't return yet a smart 
pointer because it creates unnecessary temporaries which can be costly, 
depending on the smart pointer used.  So the typedefs inside 
shifted_allocator are the way I think they should be understood by the 
containers...

Thanks,
