MARATIS.SLN from cmake  (12/0514)
-------------------------------------
stuff to fix

------------------------------------
vorbis

tone.c
line 18 alloca is undefined
line 40 M_PI : undeclared identifier
line 41 rint : is undefined
( missing math library ? )

------------------------------------
MCore

MfileTools.cpp
 - needs dirent.h on windows ?
changed to #ifdef WIN32
    #include <dirent.h>

in the project properties page, Configuration Properties/Preprocessor : add MCORE_DLL to preprocessor definitions

 ------------------------------------
MaratisPlayer and MaratisEditor:
in the project properties page,  Configuration Properties/Linker/Input,
 the directx libs (dinput8.libdxguid.libdxerr.lib) should be removed
 ------------------------------------
small tweaks :
could all projects default solution configurations be set with 'Release' 'Win32' by default ?
MaratisPlayer, MaratisEditor, Mcore and MEngine could have a common output folder
