Rename labels: follow theme if available, sane default

Fixes https://github.com/mate-desktop/caja/issues/688

*Split caja.css. Much of it can load with GTK_STYLE_PROVIDER_PRIORITY_THEME to allow themes that support Caja to set their own style. CSS required for the desktop background to show and to keep the white text suitable for most backgrounds needs GTK_STYLE_PROVIDER_PRIORITY_APPLICATION so it is loaded separately from new file caja-desktop.css

*Move all css items that must not be overridden by themes (most of them are for the desktop) to caja-desktop.css and keep those that are only needed when themes do not set them at all in caja.css
