Hmm.

There are at least two flavors of protocol "preference":

        1) "preferences" that correspond to what the individual user prefers - for example, "Show {TCP,UDP} summary in 
protocol tree";

        2) "preferences" that really correspond to how *a particular capture* should be handled.

For category 2), we might want to have both a "global" default setting (or, rather, a per-profile default setting), 
with the ability to override the default without changing it.

In addition, some of those settings might be per-conversation - and not necessarily at the level of the protocol to 
which the setting applies, e.g. you might have XXX-over-TCP and want to control how the XXX payload is dissected, on a 
per-TCP-connection basis.

"Decode As" settings are in category 2.  I could see the *default* setting for those preferences showing up in the UI 
as protocol preferences, with the "Decode As" UI controlling the override.
