Close/Keep in Dock always at the bottom

#86 What do you think about this? @elementary/ux

[Blast-City]

As far as I can see this just reorders the code and therefore the menu. Works as expected and no regressions found.

However, need @elementary/ux sign-off on whether or not the list of windows should appear first in the menu or the application specific actions such as "New Window" as this is not specifically mentioned in the issue.

Since #85 was approved wouldn't be logic to not show the windows list on the right click menu?

I think I like this change, as it's how I'd intuit to design the menu. However, I think the reason those items are currently on top is because they're farthest from the cursor; the result is that app actions end up being closer to the cursor. I don't know if that's actually a good reason for the current design, though.

If we're changing this anyway, we might be able to just clean up the code that decides how to order the menu and always order it the same way (since we don't support the dock on top).

Thoughts, @danrabbit?

I think these items are better on top, because when you have a lot of windows, you would have to scroll all the way down.

Closing since this applies to the old plank codebase and we've done a full rewrite
