Spaces Sidebar Navigation Update

The sidebar has gone through quite a few changes over the past couple of months, however instead of iterating on the existing structure we choose to redo it completley and rethink the ux.

Result: It's now possible to change all the Spaces settings from the sidebar itself, easier to get to the dashboard and the editor, and a whole lot less clutter.
