Add Race, Mana Cost and Card Type to cards in API.

[severinkaderli]

I'm working on "a lot" of changes in the client (#11) and one of those is a better / expanded filtering system. It would be great if the cost, race and card type (spell, creature) could be added to the API response of cards. That way I can implement filters for it.

Updated the API to include family, type and manaCost

{
    "civilization": "fire",
    "family": "Armored Dragon",
    "manaCost": 7,
    "name": "Galklife Dragon",
    "set": "dm-04",
    "type": "Creature",
    "uid": "81ebd0e6-94dc-44e6-958a-6df15dae091c"
}

it's called family to keep it consistent with the rest of the API, but "Race" is probably a better name for the frontend
