Have a report error button now

I added logging, and added a button for users to report problems. A window pops up and they can type the problem and their email and click submit. I worked out how to send files in a POST request, so the log file gets sent to my page, where nothing much happens yet, it just gets saved to my server (just to prove I can upload it and do something with it). I found out how to make a chatbot that can do notifications (not just reply when you type a message) that uses the RSS of your site. So now I am going to learn about RSS feeds and add one to my page. I will update it when a) a user reports a problem, and b) when there is a commit to the guide. Then, using something called 'Zapier', I'll make a chatbot for Slack and it can notify me when something happens so I can fix it :-) When I am able to get notifications of user-reported errors, I'm pretty sure that's enough for people to start using it, and I'll release an alpha build.
