Bjørn Erik Pedersen c825a73121 Support open "current content page" in browser
This commit adds a new `--navigateToChanged` and config setting with the same name, that, when running the Hugo server with live reload enabled, will navigate to the current content file's URL on save. 

This is really useful for site-wide content changes (copyedits etc.).
Fixes #3643
