Remove crawl API endpoint

[carrythebanner]

Following investigation in #620, the crawl endpoint is no longer needed as no known clients or crawlers use this endpoint.

Primary files:

• app/endpoints/crawl.js
• app/views/crawl.html
• docs/CALENDAR_API.md ("event crawl returns HTML" note at top; entire "Crawling an event" section)

Other files:

• app/app.js
• app/config.js (comment only)
• app/test/crawl_test.js
• docs/exampledata/crawl_empty.html
• docs/exampledata/crawl_15229.html

Hi @shivam0912, I noticed you'd expressed interest in this one a while back, but the issue hasn't seen any activity in over a year and I didn't find a branch or PR, so I went ahead and put together a fix in #1065.

It removes the crawl endpoint, view, test, and docs as outlined above, and bumps the API version. If you're still keen to work on this, I'm happy to step back; just let me know. Otherwise, reviews and feedback on the PR are very welcome!
