logic: Show overview of analyzed symbols after launch

* show analysed nodes as bundles in graph
* ellide node names longer than 50 chars
* sort nodes alphabetic in these bundles
* show stats of analysis in code
* error are displayed as well in overview
* added keywords overview and error
* project description can be set in .coatiproject file
* description can include links to symbols using [symbol] syntax
* updated documentation
* increased toc nesting in documentation
