Webhost: Allow Option Groups to specify whether they start collapsed (#3370)

* allow option groups to specify whether they should be hidden or not

* allow worlds to override whether game options starts collapsed

* remove Game Options assert so the visibility of that group can be changed

* if "Game Options" or "Item & Location Options" groups are specified, fix casing

* don't allow item & location options to have duplicates of the auto added options

* use a generator instead of a comprehension

* use consistent naming
