* MOD grammar generation: use Array (instead of Object) for holding
intermediate/partial matches in result Object (i.e. value of field
"phrases")
* BUGFIX when unmasking a String: if after masked charater only 1
character followed, the last character (ie. the one after the masked
character) was omitted in the result
* BUGFIX for old/deprecated umlauts encodeding/decoding: file
grammarConverter.js had been saved with ACII-encoding (now using escaped
unicode chars)
* FIX on masking a String: during generating result-String
("string-buffer"), prevent process from creating unnecessary, empty
entries
