Update adjectives.txt

Removed words with negative connotations and things that will make kids giggle at their inappropriateness. :)
removing length restriction from form
Merge remote-tracking branch 'upstream/v2.0' into v2.0
Update adverbs.txt

Same note here as for adjectives – just cleaning up things a bit.
Fixed #153, with a regression test.
Update nouns.txt
/v2/program/:shortname now includes earnableBadges info.

Note that I changed the key name from "earnable badges" (in the spec)
to "earnableBadges", as spaces in key names are weird. Changed the spec to
reflect this too.

Fixes #155.
replaced dedupe() w/ _.uniq() as per loveswords' recommendation.
new word lists
making words cute. background: https://twitter.com/chmcavoy/status/339927331399421952
Phrase generator now creates alphanumeric codes rather than naughty phrases.

e.g., 'nc8K-ppBP-eB9z-r9t9' instead of 'creepily-erect-finger'.

The alphabet used in the new "words" excludes characters that look the
same in many fonts: l, I, 1, 0, and O.

This is an alternate solution to pull request #156.
Removed uppercase chars from phrases.

This way there's no confusion between uppercase/lowercase, and the
phrases are easier to type.

The combinatorial space is still pretty big, as the alphabet is
33 characters, and with 16 letters per phrase that means
Math.pow(33, 16) == 1.977985e+24 possible phrases.

Add badge name and image to /v2/user return data
Added a lot more properties to API representations of badges.

Specifically: categoryAward, categoryRequirement, categoryWeight, categories,
ageRange, type, and activityType.

Need to document these on the wiki now, so this is one half of #146.
Implemented GET /v2/user/badge/:shortname. Fixes #159.
Push badge class info down in /user endpoint as well
