Drop IE11

[midzer]

I've found places in code where we can save some bytes by removing .keyCode. Current (optional) polyfill is for IE only, I think.

In Germany, less then 1% of users still use IE. So it's more or less dead after offical support has been dropped last year.

How about removing it for an upcoming v3?

I think it is not worth to work hard to support IE11, it means we can support only basic features, like open, next, previous, close. That's all.

I do not like dropping IE11 only to save few bytes.
If IE11 support would require extra development, then yes.

Overall, even dropping IE11, fallbacks will work on this browser, I mean click on image will still give you image (just not in modal window), same for iframe, youtube, inline.

It is already not working on IE.
