Updated x86 expression emulating

Using updated x86Emulator class from de4dot confuser unpacker

[ViRb3]

Just a note for the others why I never merged this - BeaEngine emulator (that I use) is more powerful than de4dot's Confuser emulation. While I agree that it is less portable and less safe, you should be deobfuscating in a VM anyway.
