Public test for the auto_update.

We will see what people say, if anything.
Error-catch if user tries to patch for an unknown mod

If it isn't on our package list, it will now display a helpful message
and usage info. Closes issue #95

This has no provision that parses if the user has forgotten to enter the mod
and the "unknown" is actually a ROMTYPE. I intend to tidy that up now.
Checks if user enters a ROMTYPE before the MOD and displays error/advice

Finishes all concerns with Issue #95
versioning to 2.9.86
