#590: Fix Asciidoc files in documentation causing errors

[alfeilex]

Fixes: #590

The main error occured by a missing line break of |== in projects.adoc. It looks like it traverse until Licence.adoc.

Further some links were incorrectly set to other files. E.g link:setups.asciidoc instead of link:setups.adoc.

Finally some refactoring suggested by intellij was made, because = <title> main title should be before [toc]. There are some other adoc files that have that, but it is not critical error that is also not recognized by asciidoctor-maven-plugin

LGTM. I've added a small suggestion.
