Remove Case Sensitivity from Riddles and Anagrams

Meaning, "harry potter" and "Harry Potter" would both be considered correct for a riddle/anagram. Case sensitivity can be really frustration for people, as it adds an unnecessary level of complexity and can lead to errors even when the correct answer is provided in a different case. Rules for the whether "letters need to be all small" differ throughout the sites and it would just be a simple fix which would make it all more enjoyable. I also think it would be nice if there could be multiple answers for a riddle.
