Achievements

Achievements are medals that you earn by meeting certain criteria (such as repeating a certain feat a particular number of times or answering a question of a specified type in less than a certain amount of time). Some achievements just fall into place as you play the game for a while. Others will take a lot of time and/or skill.

TO DO: write up details after clarifying which ones are implemented (a bunch of them aren't working right now) and, if missing, whether they'll be in the first release
