* all database functions return an err as the first param which is non-null for failure.
  * all wsapis handle database errors and return service unavailable to client.
  * stalled-mysql-test implements unit tests to verify proper failure behavior of all wsapis.
  * configuration parameter added to define max allowed time per query

fix char munging when postprocess is in play serving large files where unicode chars fall on chunk boundaries.  closes #1057

* include.js pointed to the production resource.
* use_minified_version was incorrectly set to true.

cache busting: add 'enable_code_version' configuration - when true return 'code_version' in session_context - also /production/XXX_vYYY.{js,css} calls now map back to /production/XXX.{js,css} - issue #226

add outbound HTTP proxy support to browserid - requires a proxy that can forward http to https traffic - closes #904

Adding i18n to wsapi. Split strings into client.po and messages.po.

Switched email from mustache to EJS templates.

Created fake locale db-LB for development and debugging.

Updated scripts.

implement a 'maximum request time' for bcrypt work.  server now fails more gracefully under backbreaking load, returning 503s to clients of the authenticate_user api.  update loadgen to be less dramatic about, but still display, 503 errors.  first part of issue #787 - a partial fix for #785 in dere too

upgrade to a branch of statsd that lazily closes ephemeral UDP ports, so that we're not allocating one UDP socket per request when under load.  closes #680

fix regression in keysigner - ensure non-default VAR_PATH is relayed to compute processes - issue #213

improve node.js version checking.  eliminate DRY violation, and use semver for robust version specification and matching.  nice yak, eh?

express our dependency on nodejs >= 0.6.3 in package.json and in code.  (note: I'm not sure package.json actually does anything useful, but it's a good place to document it)c

move generation of ephemeral database names (used in perf/unit testing) to a higher level and out of core code.  also, emphemeral database cleanup is now a responsibility of the harness running the software (test harness, or run_locally.js).  This fixes race conditions in unit tests that restart daemons (closes #557) and simplifies running local performance tests (issue #504)

public and private keys explicitly read, whenever we can't read them we go down with a hard error: closes #581, related to issue #576

in production (dev/beta/prod) use a more conventional logging format that includes timestamps.  closes #234

add the dbwriter process.   it's not yet hooked up, but starts up and runs, and included in health check.

reorganize browserid process - break out view serving and wsapi handling.  preparation for dbwriter split.  issue #460

in production (dev/beta/prod) use a more conventional logging format that includes timestamps.  closes #234

implement throttling on outbound emails: don't send emails to the same address more than once per minute - issue #430
