Document finding and adding external scripts

[technicalpickles]

I proposed this in hubot-archive/packages#60 (comment)

Basically, since we've been doing script packages, the example (or generated) package.json has the 'hubot-scripts' keyword. I already said that in the context of having a web accessible view. But it turns out, npm has a CLI way of searching packages, as well as seeing more info:

connor:examplebot technicalpickles$ npm search hubot-scripts pagerduty
NAME                   DESCRIPTION                                               AUTHOR            DATE       VERSION KEYWORDS                            
hubot-pager-me         PagerDuty integration for Hubot                           =technicalpickles 2014-12-16 2.0.2   hubot hubot-scripts pagerduty       
hubot-pagerduty-github PagerDuty Integration for checking who's on call, making… =patcon           2014-04-24 0.1.0   hubot hubot-scripts pagerduty alerts
npm home hubot-pager-me

At that point, npm opens a browser window for the homepage, where the user can figure out the next steps for installing.

We can add that to the hubot docs, along with things like how to update hubot and scripts.

I think docs/index.md would be a good place for this, but open to ideas.

@technicalpickles so if I'm following this correctly, it's just a matter of adding the instructions to the docs, then, yes?

[technicalpickles]

@jglovier that's it exactly. It's mostly finding the right place so it flows, and is easy to find.

Yeah index feels legit - at least for now.

Since #956 was merged, this is probably good to close @technicalpickles @jglovier @bkeepers?

[technicalpickles]

@geoffreyanderson Yep, thanks for the reminder!
