Refresh / update for org.topbraid.shacl 1.1.0

[Locke]

Based on the initial approach of @xristy I made the effort to refresh this plugin for the SHACL library version 1.1.0 and Protégé 5.5.0.

I tried to keep the changes of each commit small and give a short explanation to make the review easier.

Some notable changes:

• update the version from 0.2.2 to 0.3.0-SNAPSHOT
• embed all necessary dependencies within the bundled jar so that users have to download and copy only a single file
• added a less abstract "example3" to use in tests and as initial content of the editor
• separated the parsing of the report into own classes so that the results can be sorted
• deleted a lot of now unused files and methods
  • most test-resources are unused too but I was not sure if I should delete them as well

For everybody who wants to try the updated version prior to this merge I uploaded it to https://github.com/Locke/shacl-plugin/releases/tag/v0.3.0-locke-1

I developed these changes on Debian 10 (Buster) with OpenJDK 11 and tested it with Windows 10 (1809) and the JRE 8 that is bundled with Protégé 5.5.0. I also tested org.topbraid.shacl with the current version 1.2.0-SNAPSHOT
