browser support table needs to be updated

[abrin]

This page:
https://github.com/hammerjs/hammerjs.github.io/blob/master/browser-support.md

seems to be missing some useful support information:

• iOS9 support -- seems to work
• Clarification of the definition of "Desktop"
• Windows10 (with touch-screen)/ Edge browser -- seems to work
• Windows10 (with touch-screen)/ Chrome -- seems to work
• Windows10 (with touch-screen)/ Firefox -- ??

Could the table be updated
