For #25441 - Removed 'Shotgun Write' prefix from create node commands.
This makes it easier to create new nodes through the tab-shortcut menu
in Nuke.
For #25441 - The node's background colour can now be set in the profile.
Fixed #25631 - File type & settings are now retained after node creation
Previously this information would be lost after the script was first saved and never re-populated from the profile in the environment.  This is now fixed so that the file type and settings are always updated to match the current profile!
