Populate challenge lore and level lore with all enum values on initialization, instead of leaving them empty.
Fix wrong message about reset for some config options.
Added new config option "gui-settings.undeployed-view-mode" with 3 values
- 'VISIBLE' - all challenges are visible
- 'HIDDEN' - only deployed challenges are visible
- 'TOGGLEABLE' - users will be able to choose option for themself (not implemented)
Implement functionality in ChallengesGUI, where if option hidden is set, then all undeployed challenges are removed.
Implement ability to edit this option via admin Settings panel.
