Comment # 5 on bug 989563 from Raymond Wooninck

Actually both Apper and Plasma-pk-updates are using the same backend
(Packagekit). 

The actual issue of the more frequent checking is actually caused by the way
that openSUSE handles PackageKit. PackageKit has been designed based that it is
always running. However this caused on openSUSE an issue with libzypp and it
was decided that PackagaeKit is stopped after being idle for a very short time. 

Plasma-pk-updates was changed upstream and now it follows correctly the setting
if it should check daily, weekly, monthly and it no longer starts PackageKit
every hour. So it would be safe to switch to Plasma-pk-updates as that this one
works better regarding updates than Apper ever did. 

I also wiped the Apper binaries for those oS versions that has
plasma-pk-updates, as that it is a clear recommendation to use the
plasma-pk-updates package.
