Supported browser versions for Admin UI

[stennie]

Supported browser versions should be documented so users & contributors are clear on what the admin UI is expected to support.

Older browser versions may continue to work, but won't be explicitly tested or coded for.

Suggested minimum versions to consider:

• Chrome 57 (released March 2017)
• Firefox 52 ESR (released March 2017)
• Internet Explorer 11 (released June 2015 with Windows 10)
• Edge 38.14393 (released August, 2016)

Chrome has a more aggressive release schedule without Extended Support Releases (ESRs), so the latest Stable version is updated every 6-8 weeks (currently v67 released in May 2018).

@stennie thank for clarifying this, but I did find a pretty big bug in IE...

keystonejs/keystone#4769

[stennie]

@cantuket I created this as a placeholder proposal for what browser versions should be supported, but this isn't a definitive list yet. The continuous integration tests only run on Chrome & Firefox at the moment, so other browsers like IE, Edge, and Safari rely on manual bug reports and testing.

I suspect your IE11 issue is related to #3734 but need to find some volunteers to investigate the fix.

@stennie thanks, that makes sense.

I actually decided to bump this one instead keystonejs/keystone#4641 because its more recent. The initial solutions proposed wouldn't have been reliable under quite a few scenarios, but I've added some tweaks that will hopefully get us closer.
