typealiases missing?

[rsrock]

These are mentioned in the README, but don't appear to be there?

julia> using FixedPointNumbers

julia> Normed8
UndefVarError: Normed8 not defined

julia> Normed{UInt8, 8}
FixedPointNumbers.Normed{UInt8,8}

I wonder if this was a sed-like error in #63?

[vchuravy]

Just a mistake on my part when updating the README. I will fix that today.
