[ublas] _temporary_traits and remove_const

Hi Toon, Hi Karl,

I was just committing some consistency fixes to Karl's _temporary_traits 
mechanism. In particular "triangular" and "banded" removed the old typedef 
but didn't define new traits. This was breaking my Bayes++ library. I think I 
have now made all the '_adaptor' classes consistent.

I also added the comment
        // Replaced by _temporary_traits to avoid type requirements on M
infront of the commented out code. I really dislike seeing commented out code 
without a reason. I never no if the code was accidentally committed with the 
code commented out or if it had to go for a reason!

In the process of committing I see that a similar fix has already gone into 
"triangular" version 1.45 so it is nice to see I was on the right track!

I am a bit confused regarding the new 'remove_const' logic in "triangular" 
however. I have a couple of questions regarding this.
a) Why is it necessary? I don't see how the 'const'ness of M can prorogate 
into _temporary_type.
If is is necessary
b) Is it only necessary for traingular_adaptors?
c) Should it not go into "temporary.hpp"

I have merged and committed leaving in the 'remove_const'

Michael
