Document fields and methods of the FlatPage model

[Baptiste Mispelon]

The reference documentation for the flatpages.FlatPage model [1] says it's a "standard Django model", but it seems to be missing documentation for which fields and methods are defined on this model. There's a [source] link so the information isn't too hard to find, but I think a proper reference documentation would be better.

Compare for example with the documenation for contrib.User [2] which is a lot more complete.
