Code review comment for lp:~jbicha/libsignon-glib/dont-depend-on-signond

The problem is that building evolution-data-server against libsignon-glib-dev adds an automatic dependency on libsignon-glib1. I do think this is the cleanest way to solve this problem.

Unity (and Unity scopes or UOA plugins) can still explicitly depend on signond but it's too much for things like Empathy, Evolution Data Server, and Shotwell to hard-depend on tens of MB of Qt libraries for an optional feature. libwebqtwebkit4 alone is over 30 MB.
