Repack Script V2

[toto621]

I have a couple of requests :
- Add multi-lang support (instead of hardcoded text in script)
- Read "Info" text from a separate file, it's easier and smarter than search in inside script
- Explain how to approximately calculate install size and final size (explain your formula)

Basically you can make all this by adding custom messages to isl file and create an ini file with all requered information about the repacked game, read by the script at compilation. You can check WPI script from razor for ini reading stuff and the modifications I made for it for easy multi-lang support
