#2363: Chat Component API Improvements

Browse Source 
- duplicateWithoutFormatting deprecated and now works to include extra. Less maintenance required for any component implementations.
- Improved copyFormatting API to allow for retention copying.
- API to append a single BaseComponent in a ComponentBuilder, previously had to wrap a
component in its own array to do this.
- BaseComponent retain API that functions the same as from
ComponentBuilder.
