This/Self instance selector in Condo IO

It should be easier for an item to refer to itself when setting up IO connections instead of giving the item a unique ID/tag and pointing any connections to the tag

Maybe a new connection from an item should refer to itself by default instead of just “NO ITEM”

This principle comes up pretty often in object oriented programming, eg. in pseudocode
Lua has self.{property}
PHP has $this->{property}
JavaScript has this.{property}
