This removes some hackery surrounding preventing content clicks, and in
general handles auxclick as it should, firing that event on secondary
buttons (wheel/right on default setup for right-handed mouse).
* RE: BasicEvents.h - our WidgetEvent is not movable (yet), so the change that requires that wasn't included.
* Parts of this use code that was introduced in bug 1427511. For now, they were replaced with their equivalents.
Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
Backport to ESR where we don't have the ResistFingerprinting component.
