add option to explain "why"

[lnussel]

When doing a zypper dup, the system sometimes suddenly pulls in tons of packages, eg due to some weird recommends that was added in some package. libsolv now improved it's capabilities to explain reasons. There's also a new -W option to testsolv: openSUSE/libsolv@958f993

How about adding a feature to explain packages to the summary screen of zypper? Like eg pressing w and typing a package name? So we can finally figure out why eg X gets pulled in on a server :-)

Yes, WIP. This could make some things a lot easier.
