Fix setAlternatignRowColors

Well, what started as a try to simplify QTreeView ended in a mass header
murder...

What happened:
* I searched for a way to let every QTreeView honor the
setAlternatingRowcolors() setting. Unfortunately it isn't enough to just
set the global palette and set it to true. So every QTreeView is now
derived from SmTreeView
* SmTreeView registers itself with SmGlobals, so the property is set
_after_ it's constructed. It's definitely not enough to call it in the
constructor. I guess that's a bug. But it's enough to append the
SmTreeView to a QList<QWidget*> in SmGlobals and call it _after_ the
painting is done.
* As an added Bonus we can add virt. funcs to every SmTreeView at will

While at it I realized that most of the included headers were void, so
remove them. No idea what impact it has on the bin size...
