Need a "bundle list" flag that shows the mix-version each bundle was added

[bktan8]

It would be nice to have a "mixer bundle list" flag that shows the mix-version each bundle was added. For example:

bootloader (upstream bundle) 10 curl (upstream package) 20 editors (local bundle) 20 emacs (upstream bundle) (included) 20 helloclear-bundle (local bundle) 10 kernel-kvm (upstream bundle) 10 os-core (upstream bundle) 10 os-core-update (upstream bundle) 10
p11-kit (upstream package) (included) 20 perl-basic (upstream bundle) (included) 20 python3-basic (upstream bundle) (included) 20 vim (upstream bundle) (included) 20
