[Oneiric-Foundations-Topic] Boost Defaults

[Scott Kitterman]

This should get done before UDS, during toolchain upload (i.e. before the first 
autosync), but I think it's worth mentioning.

The current Boost that's default and in Main is 1.42.  Debian's current 
default is 1.46. My proposal for Oneiric is that we switch our default/Main 
version to 1.46 at the start of Oneric development and then in Debian updates 
their default prior to feature freeze, we'll assess where we are and decide if 
we should stay with 1.46 or advance.
