Some functions implemented for the Ascii struct have the same functionality as other functions implemented for the normal chars. For consistency, I think they should have the same name, so I renamed the functions in Ascii to match the names in the Char trait. * Renamed `to_lower` to `to_lowercase` * Renamed `to_upper` to `to_uppercase` * Renamed `is_alpha` to `is_alphabetic` * Renamed `is_alnum` to `is_alphanumeric` * Renamed `is_lower` to `is_lowercase` * Renamed `is_upper` to `is_uppercase` [breaking-change]
