Change PodcastQuotes to Podverse in templates

-Ugh a little convoluted, but for now the website's name is Podverse in
the templates, but most all the PodcastQuotes references in the .pys
will stay the same. We may want to change all references in the .pys
from PodcastQuotes to Podverse, and the 'pq's to 'pv's, but I'll put
that on the shelf for now.
