ui: redesigned graph overview and use new list layouting within overview bundles

* overview bundles imitate style of bundled node type
* removed bundle for built-in types
* show contents of overview bundle in vertical list layouted with new ListLayouter
* nodes starting with the same letter are grouped with the letter displayed above
* pressing the letter key will scroll to the group
* also use this list layouting for namespace & package contents
* renamed BucketGrid to BucketLayouter
* moved used functions of GraphPostProcessor to GraphViewStyle and removed GraphPostProcessor

fortune cookie message = Don't be afraid to take that big step
