Generate tweets from Metrics news feed

[irl]

Now that there is an ATOM feed, we can syndicate this via the metrics-bot accounts.

​https://metrics.torproject.org/news.atom

Will look at this this week.

This is an excellent candidate for implementation using Huginn, which hiro has a machine for on greenhost.

For now, setting to needs_information until the details of the machine are available to set this up.

Will look at this this week. hiro has provided me with details for a Huginn instance.

Ok, so I've come up with the following two agents that should consume the RSS feed and create nicely formatted tweets.

The formatter should always truncate titles so that tweets are never more than 280 chars. When it does this it should add an ellipsis.

hiro: Does this look reasonable to you?

I think I'll let it run for a while to see how it updates when we update the feed before plugging the Twitter account into it.
