minimumWidth() for TreeView in KJanusWidget

[Tobias Koenig]

Hi,

the attached patch changes the minimumWidth() of the KListView to
a width, so that all items are visible without horizontal scrolling.
Since there is a QSplitter between the listview and the rest of the
widget that shouldn't be a problem for large (nested) trees.

Ok for commit?

Ciao,
Tobias
