Warn if a lib32-$package exists and no open AVG exists #120
Description
When creating an AVG for libvorbis, warn that lib32-vorbis also exists in the repositories and most likely also needs an AVG (they have a different pkgbase).
Test case
- Create an AVG for libvorbis
- Check if lib32-libvorbis exists
- Inform the reporter via a flash message that lib32-libvorbis also exists if there is no open AVG for it.
