Added to_json() for other, lose condition, input replay

Added Utils.to_bool() utility as a workaround for Godot #27529
(godotengine/godot#27529).

+Converts a string to a bool, treating values like 'False', and 'false' as false values.
+
+This is a workaround for Godot #27529 (https://github.com/godotengine/godot/issues/27529). When converting a bool to a
+String, the String is set to "True" and "False" for the appropriate boolean values. However, when converting a String
+to a bool, the bool is set to true if the string is non-empty, regardless of the contents.
+
+This code is adapted from Andrettin's suggested fix. Per his suggestion, the result is true if the String is "True",
+"TRUE", "true" or "1", and false if the String is "False", "FALSE", "false" or "0". If the string is set to anything
+else, then it is true if non-empty, and false otherwise.
