Always show confirmation before wiping installation directory

[lyneca]

Is your feature request related to a problem? Please describe.

Wabbajack wiped my entire 600GB Modlists folder, including hundreds of hours of saves, without warning or confirmation.

My folder structure was as follows:

/path/to/Modlists
  |- LoreRim
  |- downloads

When I pressed download on another modpack, Wabbajack autofilled /path/to/Modlists as the installation path. I assumed this would then create /path/to/Modlists/[new pack name], so I hit confirm.

Wabbajack then immediately began wiping everything under Modlists/, without providing any confirmation, warning or even really any notification that it was doing so (aside from "looking for things to delete").

Describe the solution you'd like

Whenever software does a potentially majorly destructive action like this, it should always confirm. It doesn't matter if Wabbajack already installed a modpack there or any other reason, you can't just rm -rf * without asking the user.

Additionally it would be nice to have a simple bit of text that says "Your modpack will be accessible at /path/to/Modlists/ModOrganizer2.exe", so it's clear where the mod is actually going to be installed.
