Sort Classes First

[simplyalexander]

Hey, thanks for this lovely app!

One issue I often have searching the gtk online docs is that I'll do a search for, say, "revealer" and the first 10 results will be the class' associated functions ("gtk_revealer_new", "gtk_revealer_set_child", etc.) before the page for the class itself is shown.

Don't know if you agree, but classes (and I suppose namespaces, interfaces, and structs too) seem like the most important pages to return in a search, and it would be cool if they could be sorted before all the other pages.

Thanks for your consideration!!
