Update database and helper functionality in CodeIgniter

Revised database drivers, query builder, and file/inflector helpers for improved consistency and functionality. Updated copyrights, links, and standardized function names including deprecating `is_countable` in favor of `word_is_countable`. Added support for new SQL features and optimized query handling.
