What's the thinking here? I would have thought that the settings set on this page would apply to the Network Stream (with the exception of `Role Access` and `Private Feeds`, which should be removed from the Network Stream Settings page).

For example, the Network Stream should be able to exclude changes to Posts, totally independently of the settings for the Site Streams. This makes even more sense when the `Disable Site Access` option is selected.

I would propose that we:
a) Remove the `Settings for Blog` dropdown altogether
b) Remove `Role Access` from the Network Stream Settings
c) Remove `Private Feeds` from the Network Stream Settings
d) Remove `Reset Stream Database` from the Sites Stream Settings
