opProx feature (Cosmas 2)

rebase on origine/master. Review Comment #181: resolved. Squashed commit consisting of - verbosity can be switched on/off on command line. - Prox: parsing %-w1 and %+w1 correctly. - opPROX: correcting order of Prox options: WIP. - beliebige Reihenfolge der Abstands-Optionen: WIP. - Prox: beliebige Reihenfolge der Optionen: OK. - Prox: beliebige Reihenfolge der Optionen: OK. - opPROX: grammar should accept any order of prox. options: WIP. - PROX: return exact error messasge about prox options. - PROX: emit a meaningfull error message: wip. - PROX: emit a meaningfull error message: WIP. - write parsing error to AST. - trying to write error message into an error node of the AST. - PROX: Fehlermeldung in KoralQuery schreiben funktioniert. - Prox... - Error detection inside Prox done. Returning a precise error message through JSON: done. - using addError() for error messages in PROX: WIP. - Prox: reporting exact error messages: works. - PROX: Tests with RecognitionExceptions removed. All Error Codes in StatusCodes.java. - Prox: error messages for wrong prox. options. - Prox: debug output deactivated. - Prox: deleted debug output. - Prox: Test added: WiP. - Prox: 1 working tests added. - Prox: 3 more tests added. changes for Review on opPROX. changes for the review. changes for the review. opPROX: PROX_REMAIN defined as a complementary class. add. test for %.
