Update 8.x-1.x with Drupal 8 Latest Release

Patched this on Drupal 8.0.2, seems to work great, thanks! Note the .info.yml is unchanged.
For those testing this module, installing 8.x-1.0-beta1 without patching, would not show the config screen, or it's menu item.

This patch is great. It does have some little issues through.
- some listed below
- hook_permissions() does not exist anymore and should be *.permissions.yml file instead.
- Indentation should be spaces instead of tabs.

Here is a new patch attached listing that. It surely have some other points to be corrected too, I made this very quickly!

   I would have call it back_to_top_admin maybe since this is about assets for admin page only.

   Why incluing this here ? Is it because of back_to_top_js requiring it ? Then it has to be a dependency of the library in *.libraries.yml thus.

#4 patch applied cleanly and works fine. The coding standards fixes seem certainly an improvement, but further than that, I'm not qualified for code review.

Is the #4 the only that needs to be applied? And what file needs to be patched?

Patch #4 is the only one that needs appliance, on 8.x-1.x-dev branch.
You should let GIT handle this. See "Apply patch" at https://www.drupal.org/project/back_to_top/git-instructions

@Dom, I use netbeans for patching and unfamiliar with Git.

#4 is working. Thanks!
