Cloze improvements

[jadeddelta]

hello, this PR was made from the suggestion in #2532, adding the ability for developers to introduce multiple possible correct answers inside of a cloze blank, along with case sensitivity to allow for participants to input answers of different case. along with this, for convenience, the first cloze blank in the prompt will be focused upon page load.
