Content Index objects should get their own hierarchy

[cjcodeproj]

There are two classes that deal with sorting of content.

media.generic.sorting.lists.ContentIndex
media.data.media.content.movie.MovieIndex(ContentIndex)

Both of these classes should be moved to a different hierarchy. Something like media.conindex or something along those lines.

The general rule is, we do not sort actual content objects, but we build objects that are more suitable for sorting operations based on the classes or programs that need to sort the data.

Closing Notes

• ContentIndex was moved to a different file for organizational purposes.
• MovieIndex will stay where it is, and when other ContentIndex subclasses are created, this issue may be reviewed again.
