* Added converters to all relevant node implementations
* Added new annotation objects with their own factory
Change-Id: I9870d6d5eac45083929d74d2e58917d0939ca917
* Makes it simpler in the linear model because we don't have to use style: "item" for regular list items and style: "definition" for definition lists
* Enforces correct nesting through existing node rules systems
* Updates tests accordingly

* Add .process() and its helpers from ve1
* Fix applyAnnotations()
** Use data[i] rather than data[j]
** Don't add empty annotation objects for no reason
** Remove empty annotation objects
*** I thought this wasn't needed, but it is needed for clean rollbacks
* Remove unused second parameter in applyAnnotations() call
Change-Id: Ia338f62d2eaf2a76f8ef653eead05bc44757a122
* Added support for asking if a given node type can have children or grandchildren and what types of nodes can be it's parent or child
* Removed canHaveChildren methods from leaf and branch nodes and converted use of them to depend on factory to read static rules from constructor lookup by type

Neither of these nodes have elements around them, so they must override the default behavior of ve.dm.Node
