- added plaintext literals without implicit whitespace; can use implicit whitespace with "~" anywhere in EBNF, not just adjacent to regular expresseions

- ebnf.py: compiler template now calls fallback_compiler as default, rather than directly returning node

- DHParser/transform.py: has_content: rules for matching content changed: regexp must not match the complete content, nur just the beginning

- DHParser/testing.py: better inclusion of CST in test-report; asterix now simply added to the test name

appending an asterix '*' to the 'match' keyword in the test-code
