A few more deprecations

I propose to also deprecate the similarity and preference transforms
from org.apache.mahout.cf.taste.transforms and
org.apache.mahout.cf.taste.impl.transforms as I don't recall anyone ever
using them.

Any objections?

I agree, they're not efficient to apply and aren't frequently applied
these days. You'd more usually pick techniques that aren't sensitive
to popularity effects and mean/stdev of data.
