nvim: Switch basic file editor to mini.files

While we can still reach vifm through the `<leader>E` mapping, the basic
`<leader>e` file editor mapping has been switched over to the mini.files
browser.
It works somewhat like oil.nvim, in that you simply get a buffer to work
with that you can delete/move/copy/rename lines in and after doing a
synchronization (with `=`) all changes are actually applied to the
files.
Since I mostly need the quick file opening to do some quick renaming
operation or want to open an adjacent file this seems like the quickest
and most painless option to do so. For larger operations I still have
access to the full vifm experience.
