Regression: Syntax error breaks Node ^4.0.0 (active LTS) support

[nickserv]

An update to marcosc-async introduced the spread (...) syntax, which isn't supported in Node ^4.0.0 without the --harmony flag. This causes Node 4 to break with this package. I almost created an issue on marcosc-async, but I thought it would be less confusing here since this package has Node >=4 in engines while marcosc-async doesn't define engines.

Example failing build: https://travis-ci.org/litixsoft/karma-detect-browsers/jobs/173932752

Possible Solutions

• Set engines to Node >=5
• Publish a new release of marcosc-async that's compatible with Node 4 syntax and depend on that in this package (ideal solution in my opinion, since it's still an active LTS version)

@nickmccurdy, thanks for reporting, just fixed marcosc-async to work with Node 4.0 and above. Added engines member to the package, as suggested.

Should be fixed now.... please reopen if still broken.

Thanks, this fixes warnings in karma-detect-browsers.
