with macro content without having to use any special methods, we just use a new custom Property Editor value converter.
Now just need to port this over to DynamicNode too.
Obsoleted a method on the 'helper' class to something much more meaningful... hopefully we can do that with the rest of that class too.
using the new framework. Also moved PersistableMacroProperty to new assembly (it was also marked as internal).
Updated unit tests to work with Resolution and resetting resolvers.
