now the window effect has its own configuration to be turned on/off in the 
taskbar.
the only gripe i have by turning it off by default from there is that since we 
can't put new configuration ui it will be simply impossible to find.
in the kwin ui of course isn't obvious but is still an ui mean to enable it.
i would say we can do the following:
1) keep enabled by default in the taskbar config
2) keep the ui in kwin to enable/disable it and disable by default from there

in 4.5 it will go away from the kwin ui and it will get a chekbox in the 
taskbar config, disabled by default
