Feedback from Steven re excludes

>So when you exclude a file there's no confirmation (except the fact it's now in your list of excluded files). Also if you're browsing in wp-content and exclude a file you're then brought back to the root. One big thing missing too, not sure if it's on your roadmap - excluding multiple files. (checkboxes eg)

I was going to split these into different tickets but thought I'd dump them here first.

Great feedback, couple of things we should do now.

- [ ] Add an AYS confirmation when excluding a file.
- [x] Make sure we reload the excludes filelist in the correct place when someone excludes a file.

I think we can leave checkboxes for future.
