feat: Toggle showing hidden items

`ctrl` + `h` toggles the visibility of hidden files and folders per tab.
The per tab option overrides the global option. So, a user may set
hidden items to be visible by default (global option) but override it
per tab with `ctrl` + `h`.

Currently, per tab options aren't presented anywhere in the UI such as a
menu, so the hotkey is the only way to use this feature for now.
