D6184: restore horizontal scrollbar in the project manager plugin

["René J.V. Bertin"]

  I'm beginning to understand the objections from X11 users. Even with my settings horizontal scrolling behaves as if it's configured to scroll at least half the viewport width at a time. On Mac/Cocoa, horizontal and vertical scrolling are equally smooth, and that's where I did most of my testing (while replying to this ticket).
  
  I now have a working standalone implementation of a wheel event filter that removes the horizontal component, leaving only vertical scrolling under touch event control while still allowing horizontal scrolling via the scrollbar.
  See https://github.com/RJVB/wheelscrollfilter
  
  For some reason this approach doesn't have the same effect in the ProjectTreeView class. I may have overlooked something trivial but either way I'd really appreciate the help of a fresh set of eyes to help pinpoint the cause of that difference.
