Inno Setup has proven limited in its ability to uninstall because its hard to keep up to date which folders it should ask or keep and not everyone has used the Offline Installer yet wishes to use an uninstaller. This commit adds a new uninstall script which my future versions of the uninstaller will look for to delete the files. Eliminating the risk of the setup accidentally deleting your stories.
If the proper Inno Setup uninstaller is detected the script will terminate itself and launch that first, to ensure the entire uninstallation is handled. If not, it will warn you before removing anything.
It will also get rid of the virtual KoboldAI drives and we can update it trough normal git means.
