Fixed Type Scrambler for C++/CLI modules

[ElektroKill]

Hello,
I've fixed the problems with the Type Scrambler mentioned in issue #244. When protecting the provided file from the issue it now works properly. There were actually three small issues at play here.

• Checking if the method had a return type was bugged and didn't take into account modifier signatures.
• Scrambling of "void" causes errors in peverify and thus should probably be skipped.
• Disabled scrambling of members in the type as C++/CLI modules contain runtime code in that type which is not called using traditional CIL calls which can be easily analyzed. Instead, they are called from outside or by function pointers.
