`Pokemon`: Merge everything from `set`

If we forgot to validate anything else from `set` than we probably dont
care about validating. Merge it into the rest of the object.
More handlers and working calc display

- `Display.updateCalcs()` Recalcs all moves against the current pokemon
and displays the results

- `Display.p1active` and `Display.p2active` store the `Pokemon` object
we are working on. This should allow us to stop building a new one
everytime.

- Add `side` to `Pokemon` objects built through `Display.getPokemon()`

- `Display.showResult()` can take `Pokemon` objects instead of `jQuery`
objects for each side. `moveIndex` must now definitely be a number
between 0 and 3.

- Run `Display.updateCalcs()` on new species selection.
