Hob GUI tweaks v2

Here are some tweaks to the Hob GUI. This series iterates on (and therefore makes redundant) an earlier series with the same subject.

Changes include

* adding a clear icon to search entries, per Gtk+ norm
* changes to PersistentTooltip's so that the colours work better on darker themes (though there's still a problem with the link colour, which is technically a theme bug but makes our app look bad), some spacing tweaks and a change to reindent the file to match the rest of BitBake indentation style.
* add a new widget, HobAltButton, for use as a secondary button instead of gtk.LinkButton - Belen, our interaction designer, informed me that the design intends them to be buttons (and therefore have prelight and active states matching standard buttons) but that they are supposed to be implemented without relief so that the user is guided towards primary actions. I need to develop a follow on that changes the colour of the secondary button text per visual design.
* Replace HobXpmLabelButtonBox with a new HobImageButton, this is a HobAltButton subclass which is modelled after the buttons in gnome-disk-utility, where Belen informs me the buttons on the main page for Layers, Recipes and Packages are modelled after.
* Finally I include a further iterated implementation of the Layer Selection dialogue which uses some new assets provided by the design team and the HobAltButton to match the visual and interation designs more closely.

Cheers,
Joshua
