[LYN-2520] Gem Catalog - Gem Inspector / Info Panel (#718)

* [LYN-2520] Gem Catalog - Gem Inspector / Info Panel

* Extended the gem info with a directory and documentation link, binary size in bytes and added some helper functions.
* Added the gem inspector widget that hooks into the selection model.
* Info panel is vertically scrollable and based on the UX designs.
* Added a gem sub widget which holds several gem tags, a title and a description and is reused for the depending and conflicting gems.
* Extended the gem model with several new roles and data elements.
* Added more gem info test data before we got access to the real data.
