Added scoring proposal to docs
HTML generation for terms

Differentiated functions in Pretty.py for a single term and a
set of terms.
frontend hooks for voting
SeaIceConnector.castVote()
SeaIceConnector.trackTerm(),untrackTerm()

All interface hooks are there, but they're ugly. Next, starred
terms on homepage (store list in class Users).
SeaIceConnector.getTermsByUser(),getTermsByTracking()
List terms on homepage
Fixed unstarring unstarred term error
Started buttons, bad logic somewhere

See FIXME seaice/Pretty.py:164
Fixed tracking button
Start class IdPool
Finished IdPool

ice creates a pool for terms, users, and comments. Mutations
on pool are atomic, and I'm fairly certain there are no
deadlock/race conditions (no interdependence).
