to all be lazy resolvers as they are not needed instantly on app startup (not needed by the front-end) This will
make app startup a lot quicker. Fixes ActionsResolver to not use the PluginManager to resolve the types when it
is instantiating them since these are passed in the ctor. Updates all unit tests to use lazy delegate for these resolvers
and they are all passing.
This allows us in the future to use any type of data source for the dictionary. Have obsoleted the old
ICultureDictionary in the macro engines project (where it doesn't belong anyways). The new one doesn't expose
the 'Language' property to the front-end because this is a business logic class which means designers can just delete
a whole language from the db by calling 'Delete' on the object !
