Options: introduce SpecialRange (#630)

* Options: introduce SpecialRange

* Include SpecialRange data in player-settings and weighted-settings JSON files

* Add support for SpecialRange to player-settings pages

* Add support for SpecialRange options to weighted-settings. Also fixed a bug which would cause the page to crash if an unknown setting was detected.
