Added a few hacks to get it compiling on Windows 8 with VS 2012.
Moved third-party libs to libs/
Added initial CMake configuration.
Added missing cmake/FindDirectX.cmake
Fixed compile and linker problems on Windows 7 with Visual C++ 2010 Express Edition
Removed old obsolete VS 2010 project files.
Moved TiMidity to neo/libs/
Fixed crash when starting Doomclassic
Added Artistic Style 2.02.1 C++ beautifier.
Formatted code using Artistic Style for better readability.
Compile VS runtime library statically

.. so MSVCP100D.dll (from VS runtime) or similar isn't needed to run
the binaries
Comment out two noisy assertions

they spam the console in debug builds (at least on my system)
Merge pull request #1 from DanielGibson/rb_static-rt

Use static runtime, remove 2 annoying assertions
(more) GCC/MinGW support in CMakeLists.txt
Some headers needed for compilation with MinGW

* sal.h is missing in MinGW
* wine-dsound.h replaces the DirectX dsound.h which uses tons of
  annotations that are incompatible with MinGW
add .gitignore
Make idlib build with MinGW

but it probably is buggy and still has a lot of warnings.

The rest still has errors, i.e. you can't build a doom executable with
MinGW yet
Added Eclipse CDT4 - MinGW Makefiles configuration.
Added missing #include <stdint.h> for uinptr_t with MinGW.
Added retail base/ files to .gitignore
