* [Explorer] Default + Custom Criteria improvements
For Custom Criteria:
* If a custom criteria throws an error or fails to parse/load, Core no longer disables custom criteria entirely -- it now disables the problematic criteria until you update the custom criteria file and trigger a new journal/re-read (which reloads the source file).
For Default Criteria:
* Adds landable status of the body triggering the Close Ring/Belt proximity. (Requested in Discord somewhere.)
* Adds the triggering ring name to the Wide Ring criteria. (I believe also requested, can't remember now.)
