Allow RemoteViews to use BAL privileges

Remoteviews' interaction handler already grants regular BAL privileges
as any interaction with a RemoteViews originates from a user
interaction. It should normally be implied that for an user to interact
with a RemoteViews the view needs to be visible. This does not hold true
for the -1 screen (where it is still visible, but the system does not
track it as visible).
