Add sidebar_module partial and SidebarPostDecorator class.

Also did some code cleanup in
PagesControllerDecorator::populate_sidebars.

The controller will now populate left and right sidebars (only
left for now,) while the SidebarPostDecorator will provide the
markup for each post that is to be shown in a sidebar.

The plan is to further expand the system with other Sidebar-
Decorators, so each item can be rendered using the same in the
partial.
