The best grass list yet! And some other things...

• Compass now looks for grass every frame if its enabled, making it feel quite a bit more responsive.
• Added the DisableCompass configuration option.
• The grass list that Grassy Knight uses to know what is grass and what is not is now even more accurate! It is reasonably likely that all cuttable grass in the game is in the list and no uncuttable grass is in the list ✨.
• The compass (even when enabled) is set to start as invisible, so you must hit the hotkey to show it. This'll be reverted in a future release, but while the grass list isn't trustworthy this seems wise.
• Room grass count is now always visible, instead of sometimes being --, to differentiate between rooms with and without grass that was cut.
