Ed Sanders 0ce20b6e16 Create MediaWiki specific nodes to contain MW specific rules.
Heading and Preformatted nodes have rules that should only
exist under a document node in MediaWiki.

Two new node types have been created as has a new DropdownTool which
uses these. The MW init options have been changed to use the new
DropdownTool.
