ui & logic: fixes for release

* smaller indexing progress dialog with bar in the middle instead of golden ratio
* set default code snippet expand range to 3
* no minimum height for project file location element in project setup wizard
* move aggregation and inheritance edges to front when hovered or active
* push parent nodes of active nodes to back to make edges to the active child visible
* properly quit application when window is closed while confirm box is open
* properly quit application when window is closed while indexing
* only count top level nodes for count on bundle nodes
* give noLetterScore to index 0 in search index scoring
