Enable default editor keymaps for editors located outside atom-workspace

[as-cii]

Fixes atom/teletype#208

This is similar to what we do for macOS keymaps:

atom/keymaps/darwin.cson

And would fix an issue teletype users are noticing when using editor commands in the popover. Since the popover is located outside the workspace (i.e. because it is a tooltip), keyboard shortcuts are not working for Linux and Windows users. I assume this is an issue with every package that attempts to use an editor outside the atom-workspace element.

@atom/maintainers: what do you think?

/cc: @AlexWayfer, who originally reported the issue on atom/teletype.

@as-cii: Would this also fix atom/teletype#102?

[as-cii]

I don't think it would because in that circumstance we use a native input element, as opposed to an atom-text-editor. Fixing that problem should be pretty easy though; I think it should only be a matter of using the native-keybindings class on the input element.

[nathansobo]

We should really find a way to fall back to native bindings as a default instead of requiring that class.

Tested on my local windows and Linux installation. Looks good.
