- copy from legacy MVC
- get `ListBox[For]()` methods in correct places and working
- also usual stuff: `var`, `[NotNull]`, remove `IDictionary<,>` overloads
- `ListBoxHelper()` -> `GenerateListBox`
- already had all the bits needed in `GenerateSelect()`
- special-case `null` or empty `name` in GenerateSelect()
- ensure `ArgumentException` has correct parameter name
- lower-level problem affected `CheckBox()` as well
- use `ListBox()` and `ListBoxFor()` in MVC sample
- use `ListBox()` in an editor template
- add `CheckBox[For]()`, `Hidden[For]()`, `Password[For]()`, and
`RadioButton[For]()`
- also make `FormatValue()` visible to users, as it is in legacy MVC
- and spread the boxes out a bit in MyView 😺
Showcased a lot of the core pieces of Display in the sample. Some pieces are still missing such as DataType handling. The infrastructure is there to handle it in the TemplateRenderer but the model metadata providers do not construct the metadata with the data types.
