Ykkrosh 53bcba3368 Atlas: Updated wxJS to latest SVN version. Made the JS runtime have a greater lifetime than all the wx windows, to avoid garbage collection problems.
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.
