Paste in between two nodes not supporting multiple node

[lucienfostier]

Version: Gaffer 1.5.0.1-linux

Description

Pasting multiple nodes in between two nodes doesnt reconnect the outputs.
It would be nice to be able to connect multiple nodes including a chain of nodes in between two compatibles nodes.
If the connection is not possible, it would be nice to place the new nodes slightly off to the side of the current network to avoid confusion if they are not fully reconnected.

Steps to reproduce

1. Copy Grade66 and Expression 12
2. Select Constant 11
3. Paste
4. The Grade 66 and Expression 12 will be pasted as new instance but the new Grade will not be connected to the ImageTransform3
5. The new Grade and new Expression are positioned in between the Constant and the ImageTransform and appear to be connected to contribute to the output but they actually don't.
