#418 FFDec can't deobfuscate some tricks used in SecureSWF 4.5

Please, look at the attached files (I attached both secured and original files for your
reference).
I see "//Unsupported by decompiler:Empty stack;" in as2 file.
And I see
/*
* Decompilation error
* Code may be obfuscated
* Error type: ExecutionException
*/
in as3 file.
Addition - as2 file deobfuscates fine with Automatic deobfuscation enabled.
AS3 file still not deobfuscating.
Any news on it?
As I already said in other deobfuscation issues:
There are many issues about obfuscated code.
Deobfuscation technics used in FFDec are not the best ones. There is no perfect solution.
It takes a lot time to investigate where the problem lies and unfortunately I am no longer
in a mood for fixing this. If I change something about deobfuscation, other part stops
working, over and over again...
I am sorry, but I give this low priority :-(.

@focus : ffdec 1.5.2 can decompile it (the AS3 file). It's very dirty, but it is able to
produce some code, if the problem is still relevant.
Thanks, I already solved it, and I hope someday JPEXS will implement better deobfuscation
in new FFDec versions.
BTW, as2 decompiles fine in 4.0.5, thanks for that.
I think it's pretty usable in current version (8.0).

Yes, decompiles perfectly fine now, thanks!
