Mock up an "under construction" page for Gen VI pokemon.
Better construction page.

Uses pokemon objects from the db. Needs the veekun8 branch of pokedex.
Don't crash when stats are missing.
Found a use for the question mark icon!
Don't let XY ruin the comparifier.
Fix syntax error in version-icons.svg
XY version icons.
Move search: Shorten stat_change_* correctly.
Move search: Bring back shadow moves.

A stray innerjoin was causing shadow moves to be filtered out even when
they weren't supposed to be.
Don't let XY crash the pokeball calculator.

It won't tell you anything /useful/ for XY pokemon, but it won't crash.
