Add breadcrumb support to text editors
It would be good to add a breadcrumb in the top of our editors. This is how it looks like in the java plugin:
It should be available in all of our editors (ttcn3, ttcnpp, asn1, config).
breadcrumb should start with the full file path
at the end, hierarchy from the file (like functions, classes) should be added dynamically
if possible, extra icon markers (like error markers) should be implemented
