RootLayer.h: introduced a method for highlighting window tab when focus

changes.
RootLayer.cpp: window tab was properly lit only when changing focus with
the mouse. Now the same happens when showing or hidding windows.
Desktop.cpp: normal windows created after floating windows did not had
B_FLOATING_APP_WINDOW_FEEL windows in their internal list, thus when such
a window was selected to become the front most it did not show floating
app windows in front of it. Fixed that now.
