T
Glenn Maynard ccbbb2e5ec Add an optional template parameter to Preference to specify the operating type
for conversions.  This way, Preference doesn't need to know about every enum
type used with it.  (This means that you can't construct a Preference<T,U> from T,
since you don't know U, which led to the previous ScreenOptionsMasterPrefs.cpp
change.)
