Some changes to the QPEDecoration c'tor internals:

Since the current deco plugin is unloaded, when a new Deco is created
via new (even if this new deco is never used or deleted immediatly afer-
wards), we have to remember the plugin name, in case someone calls the
default c'tor (without supplying a plugin name)
