Views for different formats should be combined into one

[glacials]

Setting up different views for each format was planned so that splits file formats could be extremely different without having to muck up a single view with a bunch of conditionals.

But now that three major formats are implemented with minimal differences (SplitterZ and TST can, right now, work off of identical views, and after #6 is solved, WSplit will be able to as well), it's becoming abundantly apparent that having a view for each format is overkill.

They should be combined into one view for displaying splits from any format, and it should be called show.html.haml.
