Fix emacs keymap

[Bad_ptr]

It will be more consistent with emacs if the ctrl-w was mapped to cut(currently it is mapped to remove for mc dialogs).

Here is an example of how it could be achieved ​https://github.com/Bad-ptr/mc/commit/404ef82a5b82adb3e7f4783b619903e9e6ab98a3

I agree that Ctrl+W should be Cut rather than Remove in the Emacs keymap, but as far as I know Ctrl-D is "delete one character from the right", so shouldn't it rather be mapped to Delete as in the main keymap, if at all? Also, I think that Ctrl-H should be added to Backspace while we are at it.

Yes, you are right. I mapped it to ctrl-d because I just don't understand how keymaps works in mc.
At first I tried to comment out the Remove = ctrl-w entry and add a Cut = ctrl-w, but it didn't help(why?), then I remapped Remove to ctrl-d and it worked. Now I realized that I can unmap Remove using Remove=.
The same thing in the [editor] section with Paste = ctrl-y and DeleteLine = ctrl-y.

It seems like Delete is already doing deletion, however looking at the C code there is a difference between Remove and Delete, but I do not understand what is that difference.)

Also, I think that Ctrl-H should be added to Backspace while we are at it.

In emacs the C-h is for help, but I'm not against it as it will be consistent with the readline. (and looks like C-h is already doing backspace)
