Dscotese options fix

[dscotese]

In Firefox 60.0.2 (64-bit), selecting the descriptor type "Option" did not cause option entry fields to be displayed. I used the console to show the hidden (by default) div and was then able to create an options descriptor.

This is a case mismatch of the O in the option value (coincidentally "option") for descriptors of type "Option" in the descriptor.js file. I will create a pull request next since I've already proven the fix.

I only wanted to include the 7/1 change to descriptor.js but I guess I screwed that up. If it's possible to separate a new commit (this fix) from commits I've already made to my own fork so that if H4I wants ONLY the new commit, that's easy, please let me know how to do it.
