Rsch/indentation/fix and enhance (#85)
* fixed indentation code and added de-/activate to indentation * added tests for indentation changes * changed indentation code and tests - more changes to plantuml-indent-regexs - added more test - changed function to determine indentation level and tests accordingly - changed plantuml-indent-line and tests accordingly - changed test names and doc strings to be more consistent * more indentation tests, corrected regex for par block - the par block usually does not have any label - added database to start regex and added a test - added block tests
