Remove dependency with Allegro library in config.h file

* Created base::write24bits() function (and detect endianness with a
  special base/config.h.cmakein)
* Use _WIN32 instead of ALLEGRO_WINDOWS
* Use _DEBUG instead of DEBUGMODE
* Replaced AL_CONST with "const" in bmp_format.cpp
* Replace stricmp() with base::utf8_icmp()
