add way to filter file view by Modified/Renamed/Added/Deleted

**Is your feature request related to a problem? Please describe.**
I use git to manage my home directory, so I always get lots of new unstaged files, even with my massive .gitignore, like when I install new software. Sometimes I just want to quickly make a new commit of a small change or revert a single line without having to see hundreds of new files.

**Describe the solution you'd like**
A way to filter the file view by Modified/Renamed/Added/Deleted. This way I could quickly see what has been modified by me and commit it without having to see hundred of files. From the '?' menu I see there is already a way to filter by status, as in staged or not, but this does not help me in this situation. I would like a similar menu, but for filtering by Modified/Renamed/Added/Deleted.

Thanks a lot for lazygit, it really helped me warp my head around git and start using it.
