`exp`, `log` and friends slow. #28

https://github.com/JuliaMath/DoubleFloats.jl/pull/136 gives DoubleFloats an exp (and exp2, exp10) implementation that is around 4x faster than what MultiFloats is using. If you wanted this version to work for all levels of precision, it would take some extra engineering, but IMO, it would be worth it.
