[CIUv3] Custom Installer Ultimate v3

@andreiutzu21
@houcine80 meant to test you with older CIU source codes.
But now just test using the script in this post.

-------------------------------------------------------------------
I had previously prepared a hotfix for @mausschieber.

I didn't share it with the other users because I was waiting for @KaktoR to be available for some testing and posting the new version 3.0.0.0.u6.
So while @KaktoR is not available, I am sharing a hotfix for u5 with the fixes provided to mausschieber and some more changes I made later.

I don't know if this bug from "Error Decompressing" will be solved, but I hope so, because the changes made to the script on the 2019-08-31 were minimal and there were some bugs that have now been fixed..
Test and share if you still have the same error compiling with the new script.

If this error still happens with this script, test with older scripts and let me know what is the latest version without the error so I can check.

Thanks!
