Major .bin and extraction code overhaul
* All .cmd files now have code for searching the for the .bin folder
* This starts at the script's parent folder and moves upward
* If no .bin folder is found then print an error to the screen
* 7z has been replaced with 7za
* This is for better handling of x32/x64 usage
* This also fixed a few bugs with extracting ProduKey/MailPassView/etc
* We no longer require the full power of 7z.exe/7z.dll
* (Since wimlib-imagex will probably be used for WIM files soon-ish)
* Bugfixes
* A few calls of pushd were unsafe (without quotes)
* SFC scan no longer closes immediately
