Review request for Plasma.


Summary
-------

this patch reenables the task switching with the mouse wheel on taskbar, quite different from before now it uses an iterator on the m_windowTaskItems hash (as a bonus a little bit more readable)


Diffs
-----

  /trunk/KDE/kdebase/workspace/plasma/applets/tasks/tasks.h
  /trunk/KDE/kdebase/workspace/plasma/applets/tasks/tasks.cpp

Diff: http://mattr.info:8080/r/357/diff


Testing
-------

tested with or without tasks, with only one and potentially crashy situations like mouse wheel when plasma just started or when the active window has benn closed and all the other iconified have been addressed


Thanks,

Marco
