Fix compilation with ICC 14

ICC didn't like passing a char array to std::find:
MD3Loader.cpp(847): error: invalid type conversion: "const char *" to "const char (&)[64]"
              skins.textures.begin(), skins.textures.end(), pcSurfaces->NAME );
                                                            ^
