#26 Forms/fields/views should accommodate online help

[Jean Jordaan]

Enable inclusion of help text in a Plomino application.
E.g.
- give fields a richtext Help property that can be displayed as a [?] marker with the field, which pops up the field content.
- allow form paragraphs to be formatted as help. Such paragraphs display as a [?] marker and shows the contents as a popup when clicked.
- give form columns a Help property ..
