Deletion of Cascade Center

Comment: Building is not notable for its modern use, but clearly is historically significant as the first Warner Bros theater. It was easy to find sources, such as https://www.ellwoodcityledger.com/entertainment/local_entertainment/warner-bros-first-theater-to-reopen-in-new-castle/article_99948cdf-5d33-5321-8b8f-116c480408c2.html, http://www.ncnewsonline.com/news/local_news/council-oks-cascade-center-sale/article_9b4e15b1-98ce-5d2b-8eec-75b55aac92e5.html, and http://www.ncnewsonline.com/news/replica-of-first-warner-theater-set-for-downtown/article_b8e8c516-0ea4-5499-bc69-f1b6bc9f1e35.html - not a very thorough efore. It is mentioned in Warner Bros (as the first theater), which I have now linked. I'm surprised this isn't on the NHRP. The article needs better sourcing and cleanup, not deletion
