Lint es6 code in demo

[nzakas]

es6 environment doesn't work inline due to eslint/eslint#2705

Are there other environments you'd like added?

[Semigradsky]

I would like to be able to lint es6 code. It seems that es6 environment should allow it.

In the list rules there are rules specific to es6:

But I see Unexpected token const error

Please see the issue I linked in my previous comment for discussion of why it doesn't work.

Environments in the demo are not supplied inline, so es6 should work. However, I did try to get it to work some time ago, and I couldn't figure it out. I'll give it a try again at some point (probably when we'll be ready to merge in Espree demo).

Yeah I'd love to help get this working. Maybe I'll work on this and the espree demo thing again.

[xjamundx]

I think I figured it out...will issue a PR tomorrow

It still doesn't work for me: #137.
