Originally the Damus Purple feature was gated behind a setting which
served as a feature flag.
However, when we release, we need to enable Purple features for all
users running on a particular version.
This commit improves feature flag management by replacing the setting
with a computed property (which still points to the setting, but can be
very easily replaced)
