Raise minimum supported browser versions

[ausi]

I think we should remove support for IE 9 and 10 and also look for other code that can be removed by raising the supported browser versions.

IE9 is ok browser is dead, but with IE10 I was not so sure, there certainly still users must support the IE10.

The market share from StatCounter GlobalStats shows only 0.17% for IE 9 and 0.22% for IE 10, but 4.59% for IE 11. Is there any other reason than market share why users still want to support IE 10?

I raised the version numbers in 6605892.

The supported browsers for the next release are now:

• Firefox 52+
• Opera 48+
• Chrome 49+
• Internet Explorer 11
• Edge 14+
• Safari 9+
• iOS 9+
• Android 4.4+
• UC Browser 11.4+
• Samsung Internet 4+

UPDATE: Android stock browser got removed in favor of UC Browser and Samsung Internet.
