#82 ModularParser-getLanguages()-returns-null

- adjusts `ModularParser` to return empty instead of `null` in line 496ff to avoid NPEs
- adds new test to `ParsedPageTest` verifying a parse of plain/raw mediawiki articles as reported in #82
- fixes naming of misspelled method or field names
- fixes (many weird) typos
- adjusts JavaDoc along the path
- partially resolves #82
