504 gateway timeout template

[fpietrosanti]

In case t2w as a proxy for nginx doesn't answer (probably when a TorHS connection doesn't goes trough) the error reported doesn't show t2w error template but nginx standard error.

TEST URL: https://rusinfoik4z4rgi3.tor2web.org/ - https://rusinfoik4z4rgi3.tor2web.org/

I would suggest to answer the appropriate template directly from tor2web software

When there is a nginx 504 gateway timeout the following exception happen on t2w side

Those seems correlated to the tor log event:
Apr 01 15:34:18.558 [notice] Closing stream for '[scrubbed].onion': hidden service is unavailable (try again later).

So this event should be handled with an appropriate error that the tor server is not reachable .
