Main change: Add restrictions when adding IDs for cards and statuses. Errors are returned when an attempt is made to set an ID lower than 1, or an attempt is made to set an ID that has already been set. Additional changes: - Error types in the board packages are now defined in errors.go. - Small formatting to error messages.
