WIP adding searching capabilities in python files. was done :
- fixed stub CTN search results so that they can be accepted by search result panel
- worked on search result panel so that it can display those CTN results
- made search result panel display correctly stub search result, for variables and body matches
- EditProjectElement now opens CTN node as well as PlcOpen project nodes
