check URL of communities

[pinage404]

Add a script that checks whether the communities URL can be retrieved or not

Don’t detect the group that died from Meetup because, as always: Meetup is disappointing : it returns a 200 when a group no longer exists

This is a first step for #259

Not sure if i should add it to npm test

[pinage404]

I've quickly looked the Meetup's API, i didn't find an easy way to know if a group at a given URL exists or not

So i did an ugly scraping based on the <title>

---

Should i change something to get this merged ?

At the moment, the script outputs this :
