Simplifying the display of the error dialogs.

Using getErrorDialog which gets a curried function with the correct dialog to display in the case of an error.

merge of partially complete performance analysis work.  it is well segmented and by merging into dev more frequently we'll hopefully avert painful merge conflicts in the future.  issue #125

make userdb more real: users have any number of 'contexts' that correspond to different devices.  key material is device scoped.

create user_db which is capable of generating random users who visit random sites, with random email addresses and random passwords

move secrets.js up to the libs/ dir.  it's useful that all code that uses random strings routes through the same abstraction so that we can later improve a single function.  a central location makes this (more) obvious.

add a 'fake verification' mechanism that can be enabled for testing via an environment variable, and will return secrets via the wsapi.  add plenty of checks to ensure this never makes it into production.
