Deck summary statistics

Similar to Cardshifter/Cardshifter#137

Show a deck summary, with information such as a mana curve, number of creatures, number of spells, etc...

I think this should be displayed near the deck selection menu at the top of the deck builder.

I found Bootstrap Charts that may be a good way to achieve this in Vue.js client.
