Currently, while navigating using keyboard, the "Devices" and
"Details" rows of the GtkListBox in the sidebar don't seem to be
selected visually. Fix that by setting "selectable" property of those
two widgets as TRUE.

The devices and details rows should have distinct icons which
provide meaning. applications-system-symbolic is generic and
therefore unhelpful in both cases.
Instead use tailored icons from the icon theme, in order to
ensure that icon theme changes don't result in inappropriate
images being used.

Set icon class to sidebar-icon, and label class to
sidebar-label. This makes it more consistent with
places sidebar in Nautilus and GtkFileChooser.

As the sidelist gets more complex, managing it in CcWindow
would make it very confusing.
This patch introduces the CcPanelList, a widget that manages
the sidelist.
