Consider dropping support for IE < 8, even optionally?

[adamwathan]

Right now : is escaped as \3A instead of \: to support really old versions of IE, like 6 and 7.

This is a bit of a pain because of a bug in css-loader that strips the leading \ from these sort of escape sequences:

webpack-contrib/css-loader#578

It's been open for about 1.5 years and is apparently a difficult fix, but it only affects me personally (and other tailwindcss users) in the case of the : character.

Since market share for IE < 8 is basically zero, it would be amazing if there was a way to just use \: instead of \3A .

Thanks so much for this great library 👍

I’d be fine with releasing a new major cssesc version without escapes for legacy browsers. Care to submit a PR?

Awesome thanks, PR'd in #19, let me know if I missed anything 👍
