[boost] ublas type_traits::const_reference

From: Toon Knapen (toon.knapen_at_[hidden])

In the specialisations for double and float type_traits
const_reference is defined as being T instead of const T&.
Due to this I can't get the address of the start of the data anymore
(needed for my BLAS bindings in the sandbox).
Following will patch it :
