Import only the Folks namspace
This commit removes all remaining occurrences using Gtk;
, using Gee;
and using Hdy;
. There's a number of reasons why we're doing this, but
to list a few:
- The
Gtk
andHdy
namespaces have had issues before with types having the same name (ie HdyHeaderBar and GtkHeaderBar) which could suddenly break the build. - By omitting namespaces, it's harder to see for new contributors what the actual type is of a certain variable when they want to look up the API
- In the long term, we want to get rid of Gee, as it's clear that it's not really maintained, and has some serious performance drawbacks.
