Edge: Roadmap to making edge the default browser on Windows

[sratz]

Background

The Internet Explorer engine on Windows is still the default engine to date.
This engine however is heavily out-of-date and does not support the latest HTML/JS features imperative for modern developments.

The Edge implementation is available via SWT.EDGE flag or via -Dorg.eclipse.swt.browser.DefaultType=edge vm arg.

Goal

The goal should be to make the Edge implementation the default browser engine on Windows.

Proposal

• Use this (umbrella) issue to keep track of open issues and to categorize them by severity
• Once we have a stable enough state with no blockers, test-drive the Edge implementation by temporarily making it the default in the Platform I-Builds.
• Based on this test drive:
  • Collect more bugs and issues
  • Revert back to IE, if critical
