New element types; alternate redline formatting

[ChasBelov]

1. Allow creation of new element types (for example, character list, setting page, property list, which are used in stage plays).
2. Allow alternate formatting of redline (for example, as yellow highlighting instead of red underline).

Final Draft allows yew to create elements. One of the good things about that program.

I wish there was some way to combine the best of both of these programs into one, solid screen writing program. That would be kewl.
