Lavaboom API 2.0.2

Added

• Added a check whether an address mapping is used in the username
  reservation.
• SockJS API client for headless serverside client development.
• Onboarding emails that introduce users to the service.
• Multiple identity support (also known as email aliases).

Changed

• Moved from traditional go get-based flow to dependency vendoring
  using godep.
• Disabled most of the log output to make it easier to analyze.
• Matching for 10k most used passwords replaced with a bloom filter
  containing 17.5m leaked passwords from various hacks.

Fixed

• Cursor leakage all over the db package.
• thread.update changing date_modified field of the model, which
  resulted in invalid ordering of the emails in the web client.
  Emails in "spam" being shown as unread on the sidebar (new label
  fetching query).
• Incorrect difference checker in thread.update.
