Update minimum supported browser versions

[phil-davis]

Description

Update the minimum supported browser versions. Note that this code expects the number of the last version that is NOT supported.

1. IE - no change, <=10 is not supported, need IE11
2. Firefox - current release is 56 and previous 55, <=54 is not supported
3. Safari - bump minimum to 10, <=9 is not supported
4. Chrome - current release is 62, previous 61, <=60 is not supported

Note: The JScript that uses these numbers also has code for FirefoxESR and already knows that Firefox ESR 52 is the "OK" version. So it should also pass anyone running Firefox ESR 52.

Motivation and Context

ownCloud is tested with currently supported browser versions, so warn users if they are using an older browser version.

How Has This Been Tested?

Types of changes

• Bug fix (non-breaking change which fixes an issue)

Checklist:

• My code follows the code style of this project.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have read the CONTRIBUTING document.

Note automated CI testing happens for:

• chrome latest (=62 today)
• chrome latest-1 (=61 today)
• IE11
• Edge
• Firefox47 (because it works - but is too old to say it is supported)

Automated tests can be run locally for:

• Firefox 56 (there is an issue getting them to run automatically on SauceLabs Make UI tests on latest Firefox run in Travis+SauceLabs #29312 )

Safari tests are not automated. QA uses Safari (among other browsers) during manual testing.

This change will cause users on older browsers to get a "browser is out of date" message. That could be a user experience issue on corporate computers if browser versions are old and the end-user has no control to do anything about it. So what is the "release to the wild" process for this kind of thing?
