[arch-general] plasma-vault hard depends on networkmanager

Hey plasma-vault seems to be using networkmanager to detect connectivity for a feature in plasma-vault that disables internet upon opening certain vaults. Although this feature can be useful, not everyone uses networkmanager and it already caused an issue when I rebooted after installing updates. networkmanager seems to be enabled by default and conflicted with my current setup. I tried to build plasma-vault without networkmanager-qt but it failed. For now I am removing plasma-vault but can this be considered a bug since plasma-workspace by itself doesn't need networkmanager but it is only a optional dependency. -- Regards Jagan
