update the http_forward module to allow global request timeouts to be set, use this to implement a 15s upper bound on requests for declaration of support in development.  This should fix unit tests

when certifying secondary certs and the user has not confirmed their ownership of the given computer, certify with a short validity period

always run our little node HTTP proxy locally to constantly test HTTP proxy support which we'll have in production - issue #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.
See http://viewvc.svn.mozilla.org/vc?view=revision&revision=99911

explicitly call .removeAllListeners() during http forwarding to eliminate memory leak.  closes #839 (with extreme prejudice)

disable http agent in http_forward - it has been capping us at five simul forwarded requests per backend process (dbwriter, keysigner)

on a hard connection error during http forwarding, don't end the client reqeust, instead let the client formulate the error code and message

disable request parsing/validation on browserid (aka "webhead") - all will be performed on the dbwriter (aka "secure webhead") - issue #460 (NOTE: request validation on webhead too requires a better session cookie implementation)

initial implementation of request forwarding, cookies set from dbwriter are still not being properly passed through - issue #460

everything else is filtered.  Things like Content-Encoding shouldn't be blindly
forwarded.

Also when forwarding responses,  ensure proper casing of headers.
