Introduce achievements/badges

[LesRamer]

StackOverflow.com has badges, video-games often have achievements, and I believe Code-Wars would benefit from adding badges & achievements as well. It should be tangent-to/separate-from the honor system (i.e., it is not based on honor-points).

Here are some ideas:

[Nice Solution] : A badge you can get by having a solution that earns 3+ Best-Practices votes
[Clever Devil] : (Similar to the above) but for Clever solutions
[Revisionist] : You get by editing/correcting other katas
[Burgeoning Author] : (one-time) You get for authoring your first kata
[Prolific Author] : (one-time) You get by authoring lots of kata
[Silver Solution] : Getting 10 Best-Practice votes
[Gold Solution] : Getting 20+ Best-Practice votes
[Poly-Glot] : Getting above a 5-kyu in 3+ languages
etc... The Medal modifier (i.e., "Gold/Silver" could be extended to create ranks of badges, "Bronze/Silver/Gold/Platinum Whatever Badge".

It would be nice for a badge to be a link in the user's profile to the thing that earned the badge (i.e., the solution, comment, translation, etc.).

I would like to see these achievements listed above be added to Honor points to the Achievements section in the Stats section in the user profile. Clicking Achievements bar should see the list of achievements the user earned from requirements.
