- VS2012: build/tests

- JSON: style and exceptions catch by ref fix
- NumberParser: case-insensitive hex parsing
- Dynamic::Var: const std::string& cast operator specialization (coaxing std::string ctor)
- LocalDateTime: strftime fix (buffer too small for full tz string, use %Z instead of %z - makes no difference on windows but is more portable)
- small buildwin.cmd vsvars32.bat call fix
