Add filtering for events about testingconferences.github.io

Was just looking at creating a page just for open CFPs, but that could also be a filter. Open registrations is another. For CFPs I was just going to filter based on status matching /CFP is open/i which looks pretty standard, but registrations is harder since it's sometimes listed different ways, e.g. "early bird".

For country & continent, would you require a new field in the yml or try to get it from the existing location field?

I could see a design where below the current Navigation (Current, Past, News) we have a set of fields with checkboxes that would filter for price and location of events.

1. I think trying to match for CFPs using a regular expression would be a good first start. Slightly more complex for regular registrations like you said but if we could get it to work it would be really valuable.
2. Country is usually listed in "location". In terms of sorting, I would go with one or the other for continent or country.
