* Clarify which kinds of options actually support "random"
The current phrasing of this sentence made me expect "random" to work even on my OptionsDict option. After asking `#archipelago-dev` and checking the `Options.py` code, it's become clear that many option types don't (and can't) support "random". This is my best guess at a more correct wording.
