Remove Classic support

Maintaining Classic support has become a huge burden for this mod, since
it is designed to modify the Blizzard UI, and the UI diverges even
further between Retail and the different Classic variants with every
update.

Hence, I rather focus my efforts on Retail, and other mods.
