[Kde-imaging] Document on allowing parallel installation of libkipi

[Jean-Michel FAYARD]

Hello to all, 
one thing that has not yet been discussed (at least I think so) is how
things will not break together. Digikam, kimdaba, gwenview, showimg et
al. will have different release time, and at some point in the future
will likely expect different incompatible version of libkipi

This document from Havoc Pannington of RedHat fame explain a way to
allow easily downstream packagers to do parallel installation of
libraries. If you don't know it yet, it's worth a read.
