Uses AccessControl::GrantOnFile to set FullAccess for users for 3 xml files in installation directory. This allows for changes made to the config/ui while using the VST plugin to persist to the filesystem. Previously, a user would need to manually set "FullControl" for users for this to work. Note: I'm committing the AccessControl plugin to the repo. It's relatively small and ensures that the plugin is available in CI when the installer is run. This reduces security risk, as the plugin is currently not hosted with an available signature/checksum for verification to be downloaded on each run.
Replace unicode character with Unicode char code point to ensure the Mobius o (\u00F6) is correctly rendered in the installer.
Closes #9
