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.
For ARRAY (I haven't measured HASH_TABLE), across is VERY much slower than the explicit loop or do_all.
Even if this is also the case for HASH_TABLE, I don't object to the change. Just mentioning the issue.
