Rename descriptionEditable to custom_description with backwards compatibility

[wei]

• Rename to ${key}Editable to custom_${key} to prettify url as snake_case is preferred over camelCase in urls, such that descriptionEditable to custom_description.
• Keep backwards compatibility so existing urls with ${key}Editable will still be an alias of the new custom_${key}, and things like descriptionEditable will still function as normal.
• (Not part of this task), for future - Instead of custom_description, Perhaps we can rename all variables to much shorter url parameters like i=1&f=1&d=1&do=Description%20Overwrite&t=Dark

descriptionEditable: string

Lines 102 to 109 in 5e8f2dc

	if (currentConfig?.editable) {
	const editableValue = params.get(`${key}Editable`)
	if (editableValue != null) {
	Object.assign(newChange, {
	value: editableValue,
	})
	}
	}

This will come handy when adding language override too (#69)
