Plasma 5 epoch or no?

[Jonathan Riddell]

we're busy packaging Plasma 5

https://code.launchpad.net/kubuntu-packaging-next

Some of the packages have the same name in kdelibs4 land but most do not

http://download.kde.org/unstable/plasma/4.97.0/src/

khelpcenter (except not really cos its khelpcenter4 in kdelibs4 packaging)
ksysguard
kmenuedit
systemsettings
plasma-desktop

should we use a 4: epoch for all the plasma 5 packages for consistency or just those with the same source/binary names?
