ANN: New HTTP.jl package

@quinnj, could you tag a release for HTTP? I am having issues with take! on Julia 0.6 that seem to be resolved in the master branch for HTTP.jl.

That’s weird because the latest tag included the fix for take!. I had mistakenly made the usage take!(String, response) and @tkelman helped change it to the more idiomatic String(take!(response)).

My bad; I was accidentally using the old take!(String, response). The String(take!(response)) is indeed working as expected.
