Subject: [PATCH] Suppress Ruby std::wstring, std::string, std::basic_string
 warnings

Lib/std/std_basic_string.i:235: Warning 365: operator+= ignored
Lib/std/std_wstring.i:8: Warning 378: operator!= ignored

Correct 801 warning suppressions (which are normally suppressed in the test-suite):
Lib/std/std_wstring.i:13: Warning 801: Wrong class name (corrected to `Wstring')

Similarly for std::string when including basic_string.i class.
