  of a button

  changed styling and added icons

- quick links to files are moved downwards
  below the commit/pipeline info
- margins changed to group content into
  4 groups to clean up the interface
- visibility info reduced to icon-only and
  moved to the right of the title

Notifications button was unavailable if user wasn't member of the
project, even if protected project is available via group privileges.

Showing disabled button with explanation tool-tip is less confusing.

This closes #2846.

refactoring buttons, fixes for projects filter on the dashboard and
group page

Added Global to the drop downs and updated the label of the button to show the current level instead of `Notifications`

Replaced `this` with `@` in the coffee file and added an arrow that clearly marks the Notifications button as a drop down

Notification dropdown now shows currently active level, and also shows what the actual value of `global` is, if the project has the notification level set to global.
