sort: rework implementation

Browse source 
Rework the sort implementation to allow Auxio to leverage it's sorting
capabilities in a more powerful manner.

This is mostly the removal of stupid redunant methods and the change of
Sort overrides to sort in-place. This just gives us the option to avoid
full blown list copies in cases where such is reasonable.
