* Updated to ZDoom r3174:

- Add $edfoverride to SNDINFO for the sake of ignorability.
- Fix errors/warnings from MinGW 4.5.0 (tdm-1).
- Disable the missing field initializers warnings that -Wextra produces from GCC.
- Update zlib to version 1.2.5.
- Fixed: FxAbs::Resolve() called isNumeric() on the wrong ValueType (which is not initialized until the end of the function).
