[Foldit] Re-enable View Option hotkeys.
Several things going on. We needed to update how we were working with refresh() to make sure that the StandaloneViewOptions were being properly enabled. Then we needed to make sure that the two view windows (preset and old-style) weren't conflicting with each other with respect to the hotkey registration. There's also some missing observer attachment that needed to get fixed.
