- DHParser/examples/EBNF/EBNF.ebnf: errors in literal and plaintext definition corrected (see unit tests)

  better error reporting for mandatory continuations
- example: BibTeX.enbf: bugs fixed

- renamed project to "DHParser" to avoid conflict with an existing Python Project named "PyDSL"; also, it makes it clearer that this project is about the digital humanities
- Extended the README.md file

slightly different syntax for 'one or more'-operator; PEG-Grammar-Definition. (will not be used for PyDSL, because it PEG syntax appears to be slightly less readable than classic EBNF

- Weitere Fehlerkorrekturen; Elimination des "component"-Parameters zugunst der initialisierung des component-Feldes durch die ParserHQ-Klasse vorbereitet -> dient größerer Übersichtlichkeit der
  generierten Parser
