- Fixed in ArchiveManagerPanel.cpp one issue forward compatibility with wxWidgets 2.9.4+ if WXWIN_COMPATIBILITY_2_8 isn't set.
- Added workaround to Drawing.cpp against the crashes on exit inflicted by SFML.
- Made the LOG_MESSAGE macro variadic so as not to have to put S_FMT() everywhere around its printf-like arguments. Variadic macros are supported by Visual Studio since 2005, C++Builder since 2002, GCC since 2001, Clang, and any C++11-compliant compiler so it shouldn't cause portability issue.
- Bumped verbosity of read elements in SLADEMap.cpp to level 3.
