[Feature Request] Show a warning dialogue or offer a merging tool if .pacnew files got generated

If an package update wants to change a config file in /etc you already changed by yourself pamac will create a .pacnew file and put a warning in the install log.

But this warning is easy to miss.

My suggestion would be to open a dialog I need to click OK on with a list of the new files and from which package they got created, so I can merge the files by myself.

Or some kind of interactive merging tool would be nice. At the moment, I use "meld" to get a handy GUI to see the differences and easily merge the changes by myself.
