Option "Ensure Single Trailing Newline" has two functions and should be split out

[draeath]

The option "Ensure Single Trailing Newline" should be split out into two unique settings, one that ensures a file has a trailing newline (as is common with unix text files), and one that collapses multiple EOF newlines down. The latter would require the former being enabled.

Atom (with this package) is the only code/text editor that I know of that exhibits the behavior of collapsing EOF newlines, and there appears to be no way to disable this without also removing the insurance of a trailing newline (as some software is unhappy with configuration files that lack one).

See also discussion in #10.

I do understand the rationale behind it, and agree that it's good in general. However, there are some cases where it's a bother, which is why it ideally would be optional (especially for specific grammar, as the current combined setting is capable). Personally, I use multiple line spaces to visually distinguish areas of a file I'm working on from each other, and I often leave a trailing section with the intent to add more below it. I also cleanup/remove these before committing anything (when I work with source control, which isn't very often). This... doesn't work so well in Atom.

I "like"/accept when my file ends up with multiple lines, but not when it does not end with endline.
