Add new variable g:NERDTreeRemoveFileCmd

[kutsan]

let g:NERDTreeRemoveFileCmd = 'trash ' and everyone is happy.

@kutsan What problem is this code solving? Does vim's delete() function not do what it's supposed to do?

[kutsan]

@PhilRunninger vim's delete() function deletes given item like built-in rm command does, so it's not possible to recover since it's actually gone after invoking it. There are a lot of alternatives that adds functionality to move given item to trash. I use trash-cli for that. If you happen to delete a file with md by mistake, you can still recover from trash with let g:NERDTreeRemoveFileCmd = 'trash '.

[PhilRunninger]

That's what I suspected. Add some text to the help file, and I'll merge this.

[kutsan]

Thanks! Does it look good now?

Also there isn't any documentation for these variables:

https://github.com/scrooloose/nerdtree/blob/ed446e5cbe0733a8f98befc88d33e42edebb67d2/plugin/NERD_tree.vim#L108

[kutsan]

And by the way, I really don't like having a need for a space character at the end of the command because we can do that programmatically but original author chose to not to and it's like that for 10 years. Now sadly, we can't go back for the sake of backwards compatibility.

[PhilRunninger]

Thanks for the heads up on the missing doc. I'll add a sentence after I merge.

Also, missing:

[PhilRunninger]

I'll add those too, soon. I'll also remove the need for the trailing space.
