JosJuice ee694e327a Get rid of banner loaders and move their functionality to volumes
Having some data available in banner loaders and some other data
data available in volumes gets messy, especially with GetNames(),
which is available in both but returns different results
depending on which one is used. This change drops support
for reading names and descriptions from Wii save data.
