data: indexing java

* expanded appsettings to include java specific stuff
* added java indexer as separate project that can be build via its build script
* added dependencies for java indexer to the setup folder
* added license files for these dependencies.
* added sample project for java. this is just to test java on other machines and can be removed again in the future.
* the java parser test suite is currently uncommented because java is not running on every machine.
* added some more node types
* removed TokenComponentAccess::AccessType and replaced all its usages by using AccessKind
* moved access components from edges to nodes
* using recordReference of ParserClient for java
* removed recording access specifier of inheritance edges.
* added styles for new node types
