Removed taxonomy slug from url for Chase the Knowledge Blog & added function to functions/post-type-chase-the-knowledge.php

i.e. https://chaseplastics.com/chase-the-knowledge-category/blogs becomes https://chaseplastics.com/blogs

Dev Note: /webinars and /events will be overwritten by respective pages unless those slugs are updated or page is deleted.

Added page-events-calendar.php template specifically for the Events Calendar main page (allows for page-events.php and /events slug to work properly without conflict).
