Gtk+-3 ev-view: Set a style class on the view so it can be more easily styled
And share the style we use for other content views.

call gtk_style_context_set_background()
Even if we now render a background in _draw() with gtk_render_background,
using gtk_style_context_set_background() in realize
makes the backing GdkWindow not being completely transparent,
which enables GTK to apply optimizations during the paint cycle.
The result is, especially in clutter-gtk applications such as Documents,
scrolling in a document page is much smoother.
