IGUIObject: Cache the JSObject*, to prevent some frequent allocation while running GUI scripts. JSInterface_IGUIObject: Fixed garbage collection issues. JSInterface_IGUIObject, ScriptGlue: Changed to the JS_THREADSAFE form of JS_GetClass. Util: Avoid startup warnings on Linux caused by using unimplemented cpu_* functions that aren't needed for anything important yet. sysdep/unix: Changed to native line endings. This was SVN commit r5154.
