Subdocs & script templates. Migrate the API from User.tasks =>

User.habits/dailys/todos/rewards. Move /#/tasks & /#/options page

templates (including necessary fixes for adsense). NOTE: this commit
won't work, it depends a bit on the *next* commit with Challenges
functionality, but I wanted to separate it out a bit for clarity
