Upgrading to 7.2.0 throws SyntaxError (up to node v3.3.1)

#193 seems to have shown up again starting in 7.2.0. Using node v0.12.17 gives the following error:

>> const Hoek = require('hoek');
>> ^^^^^
>> SyntaxError: Use of const in strict mode.

various other errors show up if I upgrade to a node version up to and including v3.3.1. Upgrading to node v4.0.0 and above seems to make the errors go away.

For now, I've worked around the problem by using:

"jsonwebtoken": "~7.1.x"
instead of

"jsonwebtoken": "^7.x.x"

in my package.json

@hbaqai this should work now with last version, can you check?

@hbaqai I'm closing the issue, be free to open it if you find it happening again.
