curl required despite it not being mentioned in requirements and presented as an "alternative to curl"

[lukemim]

I hoped I could use this as an alternative to curl, especially because I couldn't find curl mentioned in the requirements and because httpful is advertised as being an "alternative to curl", but when curl is not enabled in php the library crashes with "Call to undefined function Httpful\curl_init()"

If it indeed requires curl then please do include it in the requirements and don't say it's an "alternative to curl"
