Feature Request: Add tab to Files pane to show the tree of tracked files

I would like to vote for the feature request from issue #1063.

> Related question: Is there anyway to use lazygit to browse/edit tracked files in addition to changed/staged files? I think this functionality would make lazygit the perfect tool for managing dotfiles the bare repo way as you would be able to browse and edit only the files you care about directly from lazygit. Such as with git-ls-files(1) or git-ls-tree(1): Stack Overflow source

It would be handy to be able to page back and forth between the log (graph) and the file tree. The UX for this still needs some thought, but I find myself still navigating to a gui to read files at a particular ref.
