Ugly page switcher

[aggalex]

Problem

The page switchers look off-place. They should better be integrated in the center of the headerbar, since it's only use right now is to house the settings icon.

Tip: To add a layout container to the center of the headerbar, set it as the window title using the function headerbar.set_custom_title (layout_container)

When using Go For it! compiled from git master you will get something like this:

Some options to change the icon size (shrinking the headerbar slightly) or to use text instead will also be included in the next version.
