logic: Refactored namespace activation

* show namespace name in search view when activated
* show namespace definitions in code view when activated
* no children in namespace
* no implicit nodes in overview or namespace
* Show a maximum of 10 open snippets
* Fixed bug causing nodes in GraphView to be stacked at 0,0
