Improve View Navigation #612

There are two more improvements that is possible in view navigation:

1. In Package explorer, we can have a section for license detections in that package (with links to the specific items in the License Explorer) This can be simple list just like the Data File paths in Package Explorer
2. In License Explorer, the file regions in the File region section has two types of origins, file and package, as shown by icons. Presently for both these cases we go to the respective file in table view. Would it be better to go to the respective package in this case in the Package explorer when the Detection origin is a package? This is a RFC
