Crawl the web to add new events

<<Describe idea here>>

I've already heard of some sort of API/library/SaaS for crawling pages!

Dangerous idea: create a "import from Lanyrd" button, or a CLI tool to import information from a Lanyrd event. This seems legit, since Lanyrd does not have any sort of TOS that forbids automatic crawling - and it's a Wiki, after all. However, Eventbrite do have a TOU prohibiting it, but does not cite Lanyrd there.
