Subject: [PATCH] Enable inverting homepage section styling

Add invert Param to the config file. Add the 'odd' class to the
post-holders and the 'even' class to the post-afters using Hugo if
statements instead of using JS. Marking invert = true in the config file
flips which sections are marked odd and even.
