update to use BenchmarkTools v0.0.7

[jrevels]

This will require JuliaCI/BenchmarkTools.jl#43 and a subsequent v0.0.7 tag for BenchmarkTools.

I'll probably have to do some manual test runs once this PR is ready.

This requires JuliaLang/METADATA.jl#7863 in order for Travis to pass on v0.6

I'll comment here once this has been deployed to Nanosoldier (I'm doing some cleanup work to update packages right now before running some tests, so it won't be for at least another few hours).

Guess the nightly cron job will cover this? Or does the Nanosoldier.jl code only run on the coordinator node with a fixed release Julia?

This. I'm never going to be running the server on a non-release version of Julia (right now it's the latest v0.5 release).

Alright, the new-and-improved Nanosoldier is up and running.

Nanosoldier passed a normal PR vs. master benchmark job, but I don't have time to test daily=true before the next daily job is triggered (45 minutes from now), so I'm just gonna let Nanosoldier undergo trial by fire since there's no downside to doing so compared to the current state of affairs. Fingers crossed.
