* changed naming to "Window Manager Settings" inspired by "Application Launcher Settings" and "Panel Settings"
* moved the entry into the advanced section of the menu.

[RFC]: Rename "Configure Window Behavior" to "Window Manager Settings"

Adding Plasma to get general feedback on this idea.

The context menu entry to "Configure Window Behavior" opens the
configuration of the window manager and not about the window.
In the past the shown configuration dialog only contained entries
affecting the window behavior but that is no longer true for the
complete KDE 4.x series since Desktop Effects had been added to
the menu. This change in naming reflects the situation and should
help to remove confusion.
