- model_t version was moved from using plain Paragraph to a dedicated
component `ShareWords` so that it's consistent with other models. This
allowed to move formatting to Rust and allowed the trait function to
have `words` parameter of type `Vec<TString, 33>`
- model_r ShareWords::render slightly refactored to be consistent with
the new model_t version
- mercury uses a unique version. The reason is that mercury SwipeFlow
contains also the initial screen with instructions and prompt screen at
the end.
