[Razor12911]

What to do for the test?

Step 1: Launch ConvUltra.exe
Step 2: Create a conversion
Step 3: Create a setup that uses iscu.dll, see IS_Example folder
Step 4: Move the first volume next to the setup you've created
Step 5: Run a test

Notes:
* Progress is not shown just yet and compression is not applied. (It's still just a test to see if CRC stays the same for all files or not.)
