require 'coercion' in decorator/coercion.
Representable#update_properties_from now always returns represented, which is self in a module representer and the decorated object in a decorator (only the latter one changes).
require newest rake to suppress that annoying stacktrace.
make Decorator::Coercion suppress virtus' #initialize and #to_hash so that we have control about what's happening (and not).
releasing 1.5.3.
