Support for node8

[devinivy]

When I attempted to use node8/npm5 with my application, it caught a snag trying to install this package. I didn't necessarily expect it to work, given that the readme of this module makes it clear that support only goes through node7 today– this is just a feature request. Let me know if I can be useful with more information or possibly with any newcomer-friendly contributions to this module. Here's the error I got during install,

Ohp, I just saw #825!

I'll give this another shot, and report back if I can get it to work.

I don't know what caused this originally, but all seems to be OK :) Might be worth tweaking the readme if node8 is officially supported?

TypeError: Cannot read property 'version' of null

Turns out this is happening due to a behavior change in npm5: npm/npm#16926. I recommend working around this by sticking to node v6 for now - refs mapbox/node-pre-gyp#298 (comment)

Ah, that makes sense. Thanks for taking a peek.
