More cleanup of DynamoRevit project
More cleanup of DynamoRevit.cs, greatly simplify DynamoRunner, Reactor is no longer a singleton, but instead associated with instances of DynamoRevitModel
Initialize RevitServicesUpdater in the constructor for DynamoRevitModel
Fix dynWatch3D, DynamoRunner should take workspacemodel as parameter when running, DynamoModel.HomeSpace should have the workspace explicitly set
