Made Irish-language frames own classes

Made the Irish language frames their own class, leaving a frame per language for the two that require language interfaces. This just made it less likely to mix up, and made the code more readable, especially the language change callbacks. Also renamed my variables to be more descriptive and possibly help others learn from it. New callbacks were added because of the creation of new frames for the Irish language buttons. Same thing, just changed language to Irish in the inserts.
