Overview of all included and/or excluded files

[derPinguin]

As of now you can only see how many files are included in your local/global state but not which ones.

It'd be nice if there was a list or some sort of simple file browser to see which files are actually managed by Syncthing. This would give some insights into which files are affected by the ignore patterns.

As a bonus: the possibility of deselecting included files and selecting not included files in said list/browser/overview.

I'm also looking for this as it would be helpful to non-programmers that use ignore patterns.
Just a simple modal with paginated list of files, e.g. by clicking on "local state", would be great.
