Matthias Clasen d732c869c2 gtk-demo: Add keywords to demos
Add the names of the main widgets as keywords to
our demos, but also things like "game". This helps
finding relevant demos in our growing list. You
can now for example type "label", and find the
"error states" and "links" demos showing GtkLabel
features.

/* Header Bar
* #Keywords: GtkWindowHandle, GtkWindowControls
*
* GtkHeaderBar is a container that is suitable for implementing
* window titlebars. One of its features is that it can position
* a title centered with regard to the full width, regardless of
* variable-width content at the left or right.
*
* It is commonly used with gtk_window_set_titlebar()
