Detect the new chromium-based MS Edge

[pimterry]

As noted in #21, until now Edge has been a funky beast built into the OS itself.

Now though, it's been rebuilt on Chrome, and it's effectively just another Chromium wrapper. You can detect and launch it standalone, just like anything else. It's currently still Beta, but very usable, and planned for official release in January.

This PR adds proper support for it. I've set up a Windows 10 VM and installed a whole bunch of things, and with this PR in place node cli.js --debug prints:

$ node cli.js --debug

Found 7 browsers in 20 ways within 160ms.

You can see Edge at the top of the detected list there.

The 'Edge Beta' folder is the current directory. I'm assuming in future that 'Edge' will be the official folder, but just on common sense, I don't have any hard evidence for that.
