Tube&Pipe 095: “Remove ISOGEN info”

[salariua]

In the T&P Authoring window, we need to be able to remove ISOGEN selection. I want to be able to remove the info in the “Type”, “Skey” fields. If you got it wrong and you need to remove it you can’t and you are forced to cancel the authoring window and start again. I also think you should allow custom values in the ISOGEN fields but that’s different matter.
