* Change the last bcrypt.get_rounds to bcrypt.getRounds.
* Remove the bcrypt require from tests where it is not needed.
* Remove exports.get_rounds from bcrypt.js, it has been deprecated.

The `static` process has been added to handle cachable resources and views, so
code relevant to serving those resources has been removed from `browserid`.

The `router` heartbeat now depends on both `browserid` and `static` processes being ok.
`router` now forwards wsapi writes to `dbwriter`, reads to `browserid`, and errors on unkown
or internal wsapi requests. The wsapi setup for `browserid` no longer handles forwards, though
some wsapi operations may trigger a forward to `dbwriter`.

add unit tests for __heartbeat__, includes exposing PIDs of all running daemons so tests may do stuff with them (like kill SIGSTOP)
