Title: Tests for tile (and some fixes besides)

Tile was playing fast and loose with some of its arguments, so I've changed it to be a good deal stricter in what it will accept.

The gradient is also quite broken, even in the narrow special case it implements, so I've just disabled it for now.

Tickets should be filed for implementing `TileGrad` properly and also changing Tile to accept symbolic `reps` argument, and handling dimension disagreements more like NumPy does.
