Re-upload script with fixes?

[Dinocanid]

After installing the script, there's quite a bit of things that need to fixed right out of the box either because it causes an error or it's a security hole, and they're all common issues:

• Renaming config_adopts to config. I know it's the last instruction you get after installing, but it feels like something that should be already done.
• The "usergroup mod" error, in which the script tries to fetch a usergroup that doesn't exist.
• A user being able to register with the name "SYSTEM".
• "rn" being deleted. I'm sure there's a reason for it being there, but it seems to cause more problems than it fixes. Some other measures should probably be taken to prevent users from inserting harmful code.
• This bug with the myadopts page.
• Being able to read/edit/delete another user's PM as long as you have the URL (I had to add this to my site, since it does indeed allow this on a fresh install)

Sure users could just apply these fixes themselves, but it's jarring when there are things you have to fix immediately after installing -- or as soon as possible to avoid exploits. (and it's pretty easy to agree that the "rn" bug is the most annoying thing ever)
