-Added anti-aliasing on lines
-Improved draw performance enormously
-Removed sequence ports for most nodes, current visual scripts will likely be broken now. Sorry!
-Block switches to 2d/3d editor if editing visual script
-Added cast node in flow control
-Added ability to do RPC in visual script
-Comment nodes
-Fix bug with inverted cable in connecting backwards
-Copy and paste nodes, including from different scripts
With this, visual script is almost done (missing registering custom nodes from addon).
All this is probably pretty broken, too and needs a lot of testing.
