[boost] [multi-index] partial_std_allocator_wrapper constructor

From: Daniel James (daniel_at_[hidden])

Hi,

I'm using the multi-index allocator utilities for the unordered 
associative containers implementation. Because 
partial_std_allocator_wrapper can't be constructed from the standard 
allocator, I get an error when I use a standard allocator as a 
constructor parameter. I believe it also prevents this with the 
multi-index library.

Would it be possible to apply the attached patch to fix this? (Or is 
there another way?) I added an implicit constructor, although an 
explicit one would be fine for my use.

thanks,

Daniel
