Fixed various issue with parsing string (such as \t and related),

Implemented escaping of slash '/' only in case of '</' to avoid potential issue with javascript and </script>
Many feature renaming to match Eiffel style and naming convention, kept previous feature as obsolete.
Restructured the library to make easy extraction of "converter" classes if needed in the future.
Updated part of the code to use new feature names.
