* [480x272] Fix initializer list issue with ZoneOptionValue (technically not C++11), now works x-platform as well, lowers Flash use; Spit out Zone, ZoneOption, ZoneOptionValue to own unit. (Fixes https://github.com/opentx/opentx/pull/4199/files#r94867147) * [480x272] Revert to Flash usage for ZoneOptionValue types (still fixes MSVC build). (Ref: https://github.com/opentx/opentx/commit/82dce3ee601049cf548ff4518902ab8e8fa62a0b#commitcomment-20388918 & https://github.com/opentx/opentx/pull/4199#discussion_r94835251) * Cosmetics. * [480x272] Cosmetics.
