AutomaticPlugin - Added support for logging service usage.

AutomaticPlugin - Added detection and logging output to mention if a file is most likely not packed with SteamStub.
Core - Fixed issue with AutomaticPlugin not properly initializing.
Unpacker v2.0 (x86) - Adjusted how the code section RVA is determined. (Moved a second check to 'optional feature' state for now.)
